fix: handle hex flag values with 'u' suffix and array parameters

- Strip 'u'/'U' suffix from hex literals before parsing bit positions
- Fixed array parameter syntax (argv[]) -> converted to pointer-to-pointer
- Added type conversion for char ** and char**
- SDL_init.h now parses successfully (15/16 headers working)

Still unsupported:
- SDL_iostream.h: function pointer fields in structs (complex C syntax)
