* 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" />`)

Fixes https://github.com/xamarin/xamarin-macios/issues/12457.
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.
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).
