Enable CoreCLR runtime pack for android-arm (armeabi-v7a)

Enable the CoreCLR runtime flavor for the armeabi-v7a ABI, following the
same pattern as android-arm64 and android-x64.

Changes:
- Set SupportCoreCLR=True for armeabi-v7a in Ndk.projitems.in
- Add ApiLevelNonMono metadata and corresponding property/placeholder
- Add Microsoft.Android.Runtime.CoreCLR.36.1.android-arm to workload manifest

Depends on dotnet/runtime#127225 and dotnet/runtime#126838 (API level 24).
