PrivateDecoderOMX: Consistent frame heights

- the openmax decoder outputs 'rounded' frame heights but the stream
parser picks up the full coded height e.g. 1088 height frames are
returned with a height of 1080
- this is fine in theory - unless the renderer is looking for a change in
the actual frame dimensions to trigger a reset...
- so make the frame heights consistent with the other decoders/parsers.

VideoOutputOpenGLVAAPI: Remove

- merge remaining code back into VideoOutputOpenGL
- there are still a few gotchas (all existing, not resulting from this
commit)
-- fallback to regular OpenGL output doesn't yet work when using, for
example, eglfs. It fails early and bails out.
-- deinterlacing setup is a mess. The whole thing needs refactoring now
that we have deinterlacing in the decoder as well.
-- need to add additional capability checks when intitialising the
FFmpeg hardware context. The current check does not account for codecs
that are actually unsupported by libva (e.g. mpeg4) - or indeed frame
sizes etc.
-- this leads to unnecessary multiple attempts at starting accelerated
decoding before falling back to software version.

VAAPIContext: Add a comprehensive hardware support check

- FFmpeg doesn't actually check for hardware support at all - which
causes late decoder failures and adds a significant delay while the
decoder classes work through their issues.
- on the upside, this exposes the surface formats supported by the VAAPI
implementation which will ease adding 10bit support.
