deps: Merge the servo/media repository (#42369)

This change merges http://github.com/servo/media into this repository.
It is only used by Servo and version upgrades are complicated by having
two repositories. In addition, this avoids the need to refer to
individual commit hashes in the Servo `Cargo.toml`. The hope is that
merging these two repositories will lead to better code organization /
simplification like we have seen with the WebXR support. Initiailly, the
idea was that this media support could be shared with the wider Rust
ecosystem, but I think that hasn't worked out as planned due to the fact
that it is difficult to use the various media packaes outside of the
Servo project and the fact that no one seems to be doing this.

Some changes were made when importing the code:
- The second commit in this PR addresses new clippy warnings from the
imported code.
 - GStreamer Packages are no longer renamed in the media code, so that
   they are named the same as they are currently in Servo.
 - Some examples are not ported as they require being run interactively
   and depend on older version of important libraries like winit.
   Having these dependencies in the core part of Servo isn't very
   convenient. Removed examples:
   - `audio_decoder.rs`: This is meant to be run interactively with a
     file so isn't very useful for testing.
   - Depended on winit GUI (`player` subdirectory):
     - `media_element_source_node.rs`
     - `play_media_stream.rs`
     - `simple_player.rs`
     - `muted_player.rs`
   - `siple_webrtc.rs`: Depended on `webrtc` library:

Testing: This is covered by existing tests. In addition, the job which
runs
the media examples is added to the unit test workflow.
