Fix new video format API. Fix new internal video format API, based on GstVideoFormat, to not clobber with system symbols. So replace the gst_video_format_* prefix with gst_vaapi_video_format_ prefix, even if the format type remains GstVideoFormat.

libs: add gst_vaapi_video_format_from_string() helper. Add gst_vaapi_video_format_from_string() helper function to convert from a video format string representation to a suitable GstVideoFormat. This is just an alias to gst_video_format_from_string() for GStreamer 1.0.x builds, and a proper iteration over all GstVideoFormat string representations otherwise for earlier GStreamer 0.10.x builds.

surface: add helper function to get chroma type from GstVideoFormat. Add gst_video_format_get_chroma_type() helper function to determine the GstVaapiChromaType from a standard GStreamer video format. It is possible to reconstruct that from GstVideoFormatInfo but it is much simpler (and faster?) to use the local GstVideoFormatMap table.
