win-capture: Hook Reset/ResetEx in Present* funcs

The virtual address table values for Reset/ResetEx can sometimes point
to functions that are in libraries outside of D3D8.dll and D3D9.dll, and
will cause a crash if used.  Instead, just hook Reset/ResetEx when one
of the Present* functions are called.
