winepulse: Don't rely on pulseaudio callbacks for timing.

Contains contributions from Mark Harmstone and Zhiyi Zhang.

Some devices, especially USB devices, have very irregular timing or
very long periods. Some Windows applications (The Witcher 3) are built
to expect regular, short period times, and so would underrun when the
device timing didn't match their expectations. This patch decouples
the Windows-side timing from the OS-side timing so we can meet those
applications' requirements.
