[Xamarin.Android.Build.Tests] Import tests from last regression test job (dotnet#5101)

Context: https://github.com/xamarin/QualityAssurance/pull/3646

CI and Xamarin.Android.Build.Tests have been updated to reflect the
third round of regression test auditing. The Xamarin.Android YAML
pipeline no longer contains QA test jobs, and the following regression
test categories have been removed:

 * `RuntimeTests` - Still runs on multiple devices on the [external test job][1].
 * `Hello` - Still runs on multiple devices on the [external test job][1].
 * `RegressionDeviceTests` - Obsolete tests removed, some missing coverage migrated to `SubscribeToAppDomainUnhandledException`.
 * `FastDevDeviceTests` - Obsolete tests removed, some missing coverage migrated to `IncrementalFastDeployment`.
 * `BuildPerformance` - Missing coverage migrated.
 * `AotSupport` - Obsolete tests removed, some missing coverage migrated to `NoSymbolsArgShouldReduceAppSize`.

The `dotnet` test categories have been removed as they are no longer
used as far as I can tell.  The `DotNetIgnore` category is the preferred
way to filter tests that aren't compatible with One .NET.

`AndroidUpdateResourceTest.RepetitiveBuild` has been removed, as it
appeared to be a duplicate of
`IncrementalBuildTest.BasicApplicationRepetitiveBuild`.
`BuildTest.BuildReleaseApplication` has also been removed as it is
implicitly covered by other release configuration tests.
