Full AOT Support for .NET 8+

[robertmclaws]

Implements #581

• Created new ImplementationMetadataProvider framework
• Moved current Reflection-based implementation to ReflectionMetadataProvider
• Created new AOT-based MetadataProvider
• Added a bunch of tests for both
• Added sample AOT console application
• Source generators are added to the existing package, should work for AOT without code changes

Without having a close look yet myself…any hunches on why CI fails?

[robertmclaws]

Probably because the build might need to be adjusted for the generators. AOT has additional requirements that might need to be installed for the build.

I'll take a look and drop another PR for the fix. But it should compile locally, and I can post the commands you need to make sure the right VC++ packages are installed on Windows to be able to run the AOT build.
