Víctor Manuel Jáquez Leal 301e281777 vabasedec: refactor format and capsfeature selection 
This is a simplification of the venerable
gst_va_base_dec_get_preferred_format_and_caps_features() function, which
predates since gstreamer-vaapi. It's used to select the format and the
capsfeature to use when setting the output state. It was complex and hard to
follow. This refactor simplifies a lot the algorithm.

The first thing to remove _downstream_has_video_meta() since, most of the time
it will be called before the caps negotiation, and allocation queries make sense
only after caps negotiation. It might work during renegotiation but, in that
case, caps feature change is uncommon. Better a simple and common approach.

Also, for performance, instead of dealing with caps features as strings, GQuarks
are used.

The refactor works like this:

1. If peer pad returns any caps, the returned caps feature is system memory and
   looks for a proper format in the allowed caps.

2. The allowed caps are traversed at most 3 times: one per each valid caps
   feature. First VAMemory, later DMABuf, and last system memory. The first to
   match in allowed caps is picked, and the first format matching with the
   chroma is picked too.

Notice that, right now, using playbin videoconvert never return any.
