Using arm64 in TargetPlatform node in RunSettings throws

[nohwnd]

Description

Originally posted here dotnet/runtime#42017

Forcing the <TargetPlatform>arm64</TargetPlatform> to arm64 will fail with:

Settings file provided does not conform to required format. An error occurred while loading the settings. Error: Invalid setting 'RunConfiguration'. Invalid value 'arm64' specified for 'TargetPlatform'.

This is because TargetPlatform is Architecture enum and that enum does not have arm64. There is also PlatformArchitecture and IsPlatformIncompatible and other few places that possible need update, not just the enum value.

Can be unblocked by not using that option in settings, but it should work correctly.

With the upcoming MIPS64 architecture (dotnet/runtime#42194, and in future there will be more arch/platforms supported by the runtime); if possible, imo it would scale well if the internal/hardcoded enum dependency is shifted to the executing runtime's API for such information.
