Don't return static caps that don't mean anything for the underlying codecs that are actually supported for decoding. i.e. always allocate a VA display and retrieve the exact set of HW decoders available. That VA display may be re-used later on during negotiation through GstVideoContext "prepare-context". This fixes fallback to SW decoding if no HW decoder is available.
