Limit adaptive selections to same level of decoder support

Adaptive video and audio selections will be limited to formats with
the same level of DecoderSupport and HardwareAccelatationSupport, unless
specifically allowed by new flags.

If different levels of decoder support are available, prefer primary
over fallback decoders and hardware-accelerated over software decoders
(in this order). For video, also prefer more efficient codecs, if both
are supported by hardware-accelerated primary decoders.
