.NET 6: add arm64 support to Mac Catalyst and macOS #10700
Description
- Fix generator to produce correct binding code for ARM64
- Add ARM64 support to Mac Catalyst. We already have runtime packs.
- Add ARM64 support to macOS
- Blocked on ARM64-runtime packs for macOS (Add Mono.osx-arm64 runtime pack and produce new runtime pack runtime#48531).
- Fixed in [dotnet] Build macOS/.NET for ARM64 as well. #10959.
- Add testing support in xharness.
- The runtime packs for macOS and Mac Catalyst don't work on ARM64 (MonoVM's arm64 binaries for macOS don't have Apple Silicon support runtime#52635)
- AOT-compile on ARM64 for Mac Catalyst (Mac Catalyst: AOT for ARM64 #11724).
