Full AOT Support for .NET 8+ (#582)

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
