Fix -Wincompatible-pointer-types in Win32Inc32 and Win32Dec32

Explicitly cast the `UINT *` pointer to `(volatile LONG *)` before passing it to `InterlockedIncrement` and `InterlockedDecrement` in `src/Mayaqua/Win32.c`.

This resolves a build error where passing a `UINT *` (unsigned int *) was flagged as an incompatible pointer type, because the APIs expect a `volatile LONG *` (volatile long *).
