Fall back on ::GetMessagePos() if ::GetCursorPos() fails under MSW.

In some rare but reproducible cases GetCursorPos() can fail and return without
filling in the provided point. Fall back to GetMessagePos() if this happens:
this is not ideal but clearly better than using uninitialized position or hard
coding something like (0, 0).

Closes #13664.
