On Windows, if wglChoosePixelFormat specifies cAccumBits, the best matching
PIXELFORMATDESCRIPTOR obtained should contain AccumBits information.
Some industrial software, such as CAD applications, require matching
the AccumBits information.

Windows uses a smaller alignment than gstreamer for some formats, for
example NV12. This means we cannot use MFCalculateImageSize() to get the
output sample size. Commit 7b79e3a87b1e switched to calling it instead of
GetOutputStreamInfo() to fix some game bugs.

v8: winegstreamer: Do not pass a sample size to wg_transform_read_mf().
mf/tests: Add a video processor NV12 test with a width alignment of 2.
