[ci] Add MAUI integration job

Adds a new MAUI test stage and job that will run against PR builds
targeting xamarin-android/main.

The new job will build dotnet/maui against the Android packs produced by
the PR build.  If that is successful, it will install the MAUI packs
into Androids dotnet preview sandbox, and create and build a template.
