[release/7.0] Add more type-forwarders for Xamarin.Android compatibility to mscorlib.dll and System.Drawing.Common.dll (#83137)

* Add more type-forwarders for Xamarin.Android compatibility to mscorlib.dll (#82618)

The legacy Xamarin.Android version of mscorlib.dll differed a bit compared to the .NET Framework mscorlib.dll, mostly because of additions for .NET Standard 2.1 support.

This meant that an assembly which was compiled against that mscorlib expects types there but since we didn't have type-forwarders in our mscorlib.dll shim to point them to the right assembly you'd get a TypeLoadException when running on modern .NET 6 Android.

Fixes #82193

(cherry picked from commit d8203e7)

* Add type-forwarders for Xamarin.Android compatibility to System.Drawing.Common.dll (#82839)

The legacy Xamarin.Android version of System.Drawing.Common.dll contained these types, add forwarders so we don't get a TypeLoadException when using an assembly compiled against that in modern .NET Android.

Fixes #82829

(cherry picked from commit e486f38)

* Use 7.0 version of the ApiCompat suppressions

* Fix diff
