           Summary: [cmake][MinGW] Don't use MS bitfield layout to reduce

With MS bitfileds RegisterAtOffset becomes wider than ptrdiff_t because of different alignment requirements, invoking static_assert. Instead of muting assert for MinGW like it's done for MSVC, it's a better choice to use more dense layout, as bitfields are not used in public APIs.

Also, suppress MinGW warnings from "#pragma warning" which it doesn't understand.
