Use standard GstVideoCodecState throughout GstVaapiDecoder and expose
it with a new gst_vaapi_decoder_get_codec_state() function. This makes
it possible to drop picture size (width, height) information, framerate
(fps_n, fps_d) information, pixel aspect ratio (par_n, par_d) information,
and interlace mode (is_interlaced field).
This is a new API with backwards compatibility maintained. In particular,
gst_vaapi_decoder_get_caps() is still available.

Forward declaring enums is not allowed by the C standard and aborts
compilation if the header file is included in a C++ project.

Allow MPEG-2 High profile streams only if the HW supports that profile
or no High profile specific bits are used, and thus Main profile could
be used instead. i.e. chroma_format is 4:2:0, intra_dc_precision is not
set to 11 and no sequence_scalable_extension() was parsed.
