Ask ditto to thin native libraries and frameworks when copying them to the app
bundle to remove slices for architectures we're not building for.
Also add tests.

Our min OS target versions are different between legacy Xamarin and .NET
(former supports earlier versions). The list of versions in the Versions.plist
contain all the versions supported by legacy Xamarin, but that's not correct
for .NET, so don't list any version in Version.plist that's lower than the
minimum OS version we support for a given platform.
This enables Visual Studio to set a specific `RuntimeIdentifier` for each platform when building all target frameworks in a MAUI project.

Sometimes we want to copy the entire input directory from Windows to the Mac
when executing the Ditto task remotely, and sometimes we don't.
In particular we do not want to copy the input directory when the directory on
Windows is an incomplete mirror of what's on the Mac - one scenario being when
copying the app bundle to prepare for IPA creation. The .app directory on
Windows is not complete - all the files are there (maybe? not quite sure, but
that's beside the point here), but some may be empty, because when we only
care about the timestamp for a file, we'll create an empty file on Windows to
mirror the actual file on Mac. Copying this incomplete directory to the Mac,
overwriting the correct files there, will break things badly.
However, sometimes we're not mirroring a directory on Windows, but instead we
have directories as actual build input (for instances frameworks from NuGets),
and in that case we want to copy everything to the Mac.
So this PR adds a parameter to the Ditto task to optionally copy the directory
from Windows for remote builds, and we enable this behavior when we want it -
specifically when copying frameworks.

Also rename DOTNET_VERSION to SYSTEM_DOTNET_VERSION to make it clear what it's
referring to (and to not clash with DOTNET6_VERSION which has now been renamed
to DOTNET_VERSION).
.NET 7 is right around the corner.
Change dSYM generation and native stripping to occur immediately before code signing,
in a newly minted post processing target.
Challenges:
* Both calling 'strip' and 'codesign' on an executable modifies that executable,
which means that we must make sure to not call 'dsymutil' on the same binary at
a later point unless it's been rebuilt.
* Thus we must make sure to update 'dsymutil's stamp file whenever we call 'strip'
and/or 'codesign' on an executable.
* Just like for code signing, we must store the libraries (either static or dynamic)
we post process in extension/watch/rid-specific projects, so that these libraries
can be loaded in containing projects and processed there.
* In universal .NET builds, debug symbols are created for the universal app bundle,
not for each rid-specific version of the app bundle. So I had to add logic to create
the native symbol lists (MtouchSymbolsList) for each rid-specific build, but then
collect them and merge those lists for the universal app bundle.
The existing SymbolStrip call we did right after linking the native executable has
been removed, because we have to do that after creating the dSYM (which the GenerateDebugSymbols
target does).
Also add tests.
Fixes https://github.com/xamarin/xamarin-macios/issues/14067.
Also change the key for our Info.plist entry with the version number in .NET, and document the change.
We now use "com.microsoft.<platform in lower case>" instead of "com.xamarin.ios" (for all platforms).

* Remove ObjCRuntime.nfloat (in favor of System.Runtime.InteropServices.NFloat).
* Automatically add a reference to the System.Runtime.InteropServices.Internal
package, so that developers get the new NFloat API (with operators) we've
added post .NET 6 (but don't do this for .NET 7).
* Automatically add a global using alias for
System.Runtime.InteropServices.NFloat -> nfloat. This is not behind the
usual `ImplicitUsings` condition our other implicit usings are, because
they're off by default for existing projects, and the main target for the
global using alias for nfloat is upgraded projects.
* Automatically generate a global using alias (like above) in the generator
for all code the generator compiles.
* Update xtro entries to reference System.Runtime.InteropServices.NFloat
instead of ObjCRuntime.nfloat.
* Add a workaround for a hopefully temporary issue with .NET/CoreCLR where the
wrong runtime pack is selected otherwise (without the new NFloat API, so
nothing works at runtime).

We don't sign each rid-specific bundle, but we sign the final merged app bundle instead.
This means that we must store the list of files to codesign from the rid-specific
build and load those lists before running codesign on the merged app bundle.

Rename our product assemblies to:
* Microsoft.iOS.dll
* Microsoft.tvOS.dll
* Microsoft.macOS.dll
* Microsoft.MacCatalyst.dll
This makes it easy to distinguish between legacy Xamarin and .NET whenever the
product assembly is mentioned, and I've also chosen the platform part of the
name to match how the platforms are named elsewhere (this also makes it
possible to simplify our build logic, since we can remove a lot of special
casing).
Fixes https://github.com/xamarin/xamarin-macios/issues/13748.
Add support for the PublishFolderType metadata on Content and BundleResource
items, which makes it possible to change the location in the app bundle for
these items (this was possible to do before with the Link metadata), but most
importantly it also makes it possible to choose to *not* bundle these items in
the app bundle (which was not possible before with the Link metadata, nor any
other means).
At first I thought setting CopyToPublishDirectory /
CopyToOutputDirectory=Never would accomplish that, but it turns out we don't
honor those, and since we already have this behavior of ignoring
CopyToPublishDirectory / CopyToOutputDirectory in legacy Xamarin, I didn't
want to change it in .NET.
So I added support for honoring the PublishFolderType metadata instead, which
is new and we already support for other item groups. This is accomplished by
adding all Content and BundleResource items with PublishFolderType set to the
ResolvedFileToPublish item group (where we already handle any
PublishFolderType values), and then we ignore such Content and BundleResource
items in our CollectBundleResources task.
Also update the documentation and add tests.
Not embedding third-party libraries in the binding assembly is the future, and
let's try to enable it by default starting with .NET.

We need to use better default values for `$(VerifyDependencyInjectionOpenGenericServiceTrimmability)`.
This feature switch ensures that DynamicallyAccessedMembers are applied correctly to open generic types used in Dependency Injection.
In the base SDK, this switch is enabled when `PublishTrimmed=true`. However, iOS apps don't set `PublishTrimmed=true` until a Target. So devs are missing out on this validation.
Conversely, in published apps, we don't want to pay the cost of doing this validation. It was showing up in startup profiles on Android. So turning the feature switch off in Release builds (builds without debugging enabled).
Port of 90f546cacc
Note, in Android we used `PublishTrimmed` to set this property, but in iOS `PublishTrimmed` isn't set yet. So I followed the same pattern as `UseSystemResourceKeys`, which is the same scenario - when a dev is developing the app vs. a production build.
* Propagate the IsAppExtension variable correctly.
* Don't try to call mono_domain_set_config for app extensions in .NET.
It doesn't look like it's needed, and it also immediately aborts anyway, so
if it turns out to be needed, another solution would have to be implemented.
Fixes https://github.com/xamarin/xamarin-macios/issues/13742.
Include all files in the project's Resources subdirectory as BundleResource
items (except .DS_Store files, which are pretty omnipresent on macOS).
Also, contrary to the other default includes, add a condition so files are
only included if we have a resource prefix (typically "Resources"), otherwise
the entire hard drive might be included, and that's not really what we want.

* Make Runtime.Arch a readonly field.
* Tell the AOT compiler Runtime.Arch is a constant value.
* Tell the linker to stub out the method we use to fetch the current
architecture from native code (it turned out a bit complicated to set the
Arch field when it's readonly - the solution I came up with was to call a
P/Invoke).
Test case (size of the main executable): link all (debug)
* Before: 33.522.704 bytes
* After: 33.506.112 bytes
* Difference: -16.592 bytes (-0.05 %)
There were no size differences in release mode, nor were there any size
differences in the "don't link" test, neither for debug nor release mode.

Make note about:
* Caveat with regards to IntPtr constructors having to be manually changed to
be NativeHandle constructors.
* Moving NSFileProvider types.
This type has been obsolete for over 3 years, it hasn't been updated in many
more years, and there are multiple newer and better alternatives available.
This meant we could remove a few more other (private/related) types as well.
Mono will eventually use functions from the Compression framework to
decompress ICU data files during the runtime's initialization. Prepare
for this by linking against the compression framework.
Also see https://developer.apple.com/documentation/compression?language=objc.
This speeds up builds significantly when the linker is disabled.
Test case: building tests/dotnet/MySimpleApp for macOS.
* Before: 37s
* After: 9s
* Difference: 26s (4x faster)
Test case: run the .NET tests
* Before: 2h55
* After: 1h43
* Difference: 1h12 (1.7x faster)

* Use 'ObjCException' instead of 'MonoTouchException' as the managed exception
type wrapping an NSException for all platforms in .NET (that was already the
case for macOS, so no change there).
* Make the ObjCException class behave like the MonoTouchException class does.
* Move the ObjCException type to the ObjCRuntime namespace in .NET.

Also make the (NativeHandle) constructor protected instead of public, to make
it clearer that it's not for public consumption.
And modify the template tests to execute the template if we can.
Fixes https://github.com/xamarin/xamarin-macios/issues/13979.
This turned out a bit complex, because numerous ModelIO APIs were initially bound
with wrong matrix types, and had to be rebound later (our matrix type was transposed
with regards to the native matrix type). The new versions often had to use worse
names, so that's being fixed now. This means that numerous tests had to be updated,
because the original API now returns non-transposed matrices.
It seems that MSBuild doesn't always automatically convert directory
separators for relative paths, so we have to do it ourselves.
Thanks to @lauxjpn for diagnosing this and coming up with a fix.

## Problem
Template package does not appear on nuget.org correctly, as `packageType` in nupkg is set to `DotnetPlatform`.
## Solution
Disabled loading Microsoft.DotNet.SharedFramework.Sdk for template package build.
it doesn't seems to be needed and overwrites PackageType to DotnetPlatform, even though initially it is correctly set to 'PackageType'
