Fixes https://github.com/dlang/dmd/issues/21271 Redefine the compatibility macro in terms of C99's `_Pragma()` instead of ignoring it. Clang and GCC will replace `_Pragma()` with `#pragma` directives in the preprocessed output, while cl.exe will actually convert it back to `__pragma()`. This is still a better situation than before as ImportC partially supports `__pragma()`.
