tonihei b3981be8b9 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.

# Release notes
### 1.0.0-alpha01
AndroidX Media is the new home for media support libraries, including ExoPlayer.
The first alpha contains early, functional implementations of libraries for
implementing media use cases, including:
* ExoPlayer, an application-level media player for Android that is easy to
customize and extend.
* Media session functionality, for exposing and controlling playbacks. This
new session module uses the same `Player` interface as ExoPlayer.
* UI components for building media playback user interfaces.
* Modules wrapping functionality in other libraries for use with ExoPlayer,
for example, ad insertion via the IMA SDK.
ExoPlayer was previously hosted in a separate
[ExoPlayer GitHub project](https://github.com/google/ExoPlayer). In AndroidX
Media its package name is `androidx.media3.exoplayer`. We plan to continue to
maintain and release the ExoPlayer GitHub project for a while to give apps time
to migrate. AndroidX Media has replacements for all the ExoPlayer modules,
except for the legacy media2 and mediasession extensions, which are together
replaced by the new `media3-session` module. This provides direct integration
between players and media sessions without needing to use an adapter/connector
class.
