* Add 'ImplicitUsings=true' to all the templates.
* Make the implicit global namespaces C#-only.
* Add the implicit global namespaces to the 'Using' itemgroup instead of the
'Import' itemgroup.
* Make sure the global namespaces are set from AutoImport.props, so that the
user may remove any global namespace they don't want in their project file
(by doing something like: `<Using Remove="Foundation" />`)

.NET doesn't support executing other targets/tasks when doing "dotnet run".
However, we need to (like we do for our current "Run" target), so implement a
rather simplistic/hacky workaround by making "dotnet run" just do "dotnet
build /t:Run".
It doesn't support everything that "dotnet run" does (for instance it doesn't
support the /no-build flag), but it should work for most use cases.

NuGet doesn't support preserving the executable bit for files in *.nupkgs
(which are just zip files), so .NET implemented a [temporary
workaround](https://github.com/dotnet/sdk/pull/17299) for workload installs,
where they hardcoded files that should be executable.
This isn't really sustainable, and they'll remove their workaround, so we need
to use their supported method of specifying the file permissions: a
data/UnixFilePermissions.xml file.

Converts the Microsoft.iOS.Windows.Sdk NuGet package into a proper
[workload SDK pack][0]. The entry point for this pack has been changed,
and it is now imported through the `WorkloadManifest.targets` file
included in `Microsoft.NET.Workload.iOS`, rather than being imported
directly from `Microsoft.iOS.Sdk`.
Import ordering has otherwise changed slightly. The following files are
now imported before the majority of the `Microsoft.iOS.Sdk` (and the
majority of the .NET SDK targets):
* Xamarin.iOS.Common.Before.props
* Xamarin.iOS.Common.Before.targets
After this the majority of the .NET SDK targets will load, followed by
the `Microsoft.iOS.Sdk` targets. Finally, everything declared in the
`<AfterMicrosoftNETSdkTargets/>` hook loads, which consists of:
* Microsoft.iOS.Windows.Sdk.targets
* tools/msbuild/*

In the latest .NET 6, our Workloads.targets is imported earlier in the build. This
requires a few changes, because we still need to run most of our logic later in the
process, which we do by adding targets files we want imported later to the AfterMicrosoftNETSdkTargets
property.
What we're loading as soon as possible:
* Our version information (Xamarin.Shared.Sdk.Versions.targets)
* The supported OS versions (Microsoft.<platform>.Sdk.SupportedTargetPlatforms.targets)
* The default OS version (Xamarin.Shared.Sdk.TargetFrameworkInference.targets).
This is all information that the .NET build require early on.
Changes:
* Rename all files that are loaded early to *.props.
* Updated documentations to reflect these changes.
* Remove Microsoft.<platform>.TargetFrameworkInference.targets, these files aren't
used and don't contain anything useful.
* Move the logic to calculate _ComputedTargetFrameworkMoniker has been delayed
to later, because it needs TargetFrameworkMoniker set.
The template takes each platform as input, and adds a TargetPlatformIdentifier condition
to the item groups.
This also means removing Xamarin.Shared.Sdk.DefaultItems.props, and put all the generated
logic into Microsoft.<platform>.Sdk.DefaultItems.props.
We can't use an identical default items file for all four platforms, because the
file is loaded once for each platform, and if the file is identical it means it'll
get repeated four times (and everything included by default will be included four
times, ending up with build errors).
Create the various NuGet packages to support .NET 5+. The packages are
currently empty (and not very useful), but the actual content will come later.
The current set of NuGet packages are (this list is duplicated for each
platform: iOS, tvOS, watchOS and macOS):
* Microsoft.iOS.Sdk: currently contains the basic MSBuild targets files for an
MSBuild Project SDK. Will eventually contain all the build logic. Might also
eventually contain other tools (mlaunch, bgen, etc.), but these might also
end up in a different package.
* Microsoft.iOS.Ref: will contain the Xamarin.iOS.dll reference assembly.
* Microsoft.iOS.Runtime.[RID]: will contain architecture-specific files
(libxamarin*.dylib, the Xamarin.iOS.dll implementation assembly, etc.):
The NuGets built on CI are automatically published to a NuGet feed.
The versioning for the NuGet packages required a few changes: OS bumps are now
changed in Make.versions instead of Make.config (this is explained in the
files themselves as well).
