feat: Implement AOT Direct Calls for NativeScript iOS Runtime

- Added AOTDirectCalls.h and AOTDirectCalls.mm to support direct Objective-C calls, bypassing libffi.
- Introduced aot-config.json to define methods and block patterns for AOT generation.
- Created scripts/generate-aot.py to automate the generation of AOT stubs based on the configuration.
- Updated Interop.h and Interop.mm to integrate AOT functionality.
- Modified MetadataBuilder.h and MetadataBuilder.mm to utilize AOT direct calls for method and property access.
- Adjusted project.pbxproj to include new AOT files in the build.
