winegstreamer: Expose the MF_MT_VIDEO_ROTATION attribute.

The stricter checks imposed by commit
ac39b313b618ab8d1613302c3604ba505afff0df, while being valid in general,
require that media source attaches to media types the attributes that
application can request.

This patch exposes the MF_MT_VIDEO_ROTATION attribute, which is for
example requested by Legend of Keepers.
