Fixes https://github.com/mono/mono/issues/10602 .
From the issue:
```
We need to enable this to support the system assemblies conflict
resolution which we now rely on for any new packages to enhance
developers experience and get us out of dependency on specific package
versions.
```
* [msbuild] Set 'CopyNuGetImplementations' to true for app extensions. Fixes#4235 and #4237.
In Xamarin.iOS.Common.targets, just before the _CompileToNative target, we
modify the mtouch references to ensure that we get the lib assemblies for
nugets, and not the ref references:
9e31d07ecc/msbuild/Xamarin.iOS.Tasks.Core/Xamarin.iOS.Common.targets (L784-L791)
This logic removes nuget references, and then re-adds any copy-local dll
references.
This works fine in executable projects, but not in library projects (aka
extensions), because nugets aren't copied for library projects:
cf4b0a12cf/src/Microsoft.NuGet.Build.Tasks/Microsoft.NuGet.targets (L86)
So we need to set the CopyNuGetImplementations variable to 'true' for our
library projects.

* [tests] Redirect MSBuildExtensionsPath to MSBuildExtensionsPathFallbackPathsOverride when running msbuild for package reference tests.
This fixes a problem where nuget restore would fail for projects with
PackageReferences, because a variable would be empty and msbould would try to
write to /:
nuget restore ../MyAppWithPackageReference/MyAppWithPackageReference.csproj
MSBuild auto-detection: using msbuild version '15.0' from '/Library/Frameworks/Mono.framework/Versions/Current/lib/mono/msbuild/15.0/bin/'.

This will become unnecessary when PR #4111 is merged.
* Add Xamarin.Mac test showing that fix is not needed (?!?)
* Add AppExtension test with packagereference
* Make extension actually have json code generated
* Fix ProjectTypeGuids of checked in extension projects, as they were not openable in VSfM
* XM extension test now correctly fails
* Now that we have a failing test, fix XM same as rest of platforms
* Disable XM tests due to msbuild redirect sadness
* Disable iOS tests as well due to #4110
* Disable iOS tests by using the Ignore attribute.
Disable tests by using the Ignore attribute, because just commenting out the
TestCase attributes makes the test fail:
1) NotRunnable : Xamarin.iOS.Tasks.ProjectReferenceTests.BasicTest
No suitable constructor was found
This is part of PR 2430: avoid duplicating degine constants if they exist. This commit splits the condition and definition of the properties in two, because xbuild doesn't support the regex part in a condition. msbuild does, but we need to support both.
The previous change had the fault of considering __UNIFIED__ANYTHING__ the same as __UNIFIED__ and if a user set that property, then he would lose the other (pointed out by jstedfast in the PR).
This commit fixes that.
In VS the property page for Build will show whatever is in DefineConstants, and then save it. Without this, that means that any time the Build page is saved, it duplicates the constants.
This fixes bug#32765: Bug 32765 - Conditional compilation symbols are duplicated everytime I reload the project or restart visual studio (https://bugzilla.xamarin.com/show_bug.cgi?id=32765)
Mono's fork of msbuild uses a `$(_DebugFileExt)` property to specify
the debug file extension (.pdb/.mdb) to use. It defaults to .pdb. So,
with XI/XM, .mdb files don't get copied to the output folder.
We also add a `$(FscDebugFileExt)` property, which allows our default of
`.mdb` to be overridden.
But the `$(_DebugFileExt)` support is not in upstream msbuild yet. So,
we can't ask the F# upstream to add it. Hence, this is being added to
our FSharp target files. Once, all this is upstream, we can remove the
overrides from our files.
