Improve codec autoselection logic

- Deprioritize codecs that don't have hardware decoding rather than rejecting them outright
- Allow AV1 to be negotiated with autoselection if no other codec is available
- Take into account YUV444 preference when picking an optimal codec
- Arrange codec preference in ascending order of computational complexity when hardware decoding is unavailable
