winegstreamer: Introduce an intermediate media format structure.

The fundamental idea here is to provide a type which can be used in the unixlib
interface. Obviously GstCaps can't be used from PE, and while AM_MEDIA_TYPE can
in theory be used from the Unix library, allocation of the format block makes
things a little tricky. Moreover, we'd ideally like to use the same backend for
DirectShow and Media Foundation, and while it wouldn't be a problem currently,
in general AM_MEDIA_TYPE is not quite expressive enough to translate from
GstCaps to IMFMediaType, and the latter can't be used from the Unix library.
