Pull Request Overview
This PR fixes static virtual method (SVM) delegate creation that was causing crashes when creating delegates to SVM methods that don't require generic dictionary lookups. It also includes a drive-by fix for vtable handling in NativeImageLayout that was causing DAC crashes in debug builds.
Key changes:
- Adds type handle setting for static methods during method decoding
- Fixes vtable declaration for NativeImageLayout to work properly with DAC
- Removes test exclusions that were previously failing due to the fixed issue
