Win32: Guard timeapi.h include for MinGW compatibility (#1345)

* bugfix/mingw-timeapi

* fix: clean up Windows timer includes

- Removed legacy GCC-specific include block.
- Added compiler-specific headers:
  - MSVC (_MSC_VER): includes <timeapi.h> and links winmm.lib
  - Other compilers: includes <mmsystem.h>
- Ensures cross-compiler compatibility and avoids duplicate headers.
