Upgrade rodio to 0.21 (#34368)

Hi all,

We just released [Rodio
0.21](https://github.com/RustAudio/rodio/blob/master/CHANGELOG.md)
:partying_face: with quite some breaking changes. This should take care
of those for zed. I tested it by hopping in and out some of the zed
channels, sound seems to still work.

Given zed uses tracing I also took the liberty of enabling the tracing
feature for rodio.

edit:
We changed the default wav decoder from hound to symphonia. The latter
has a slightly more restrictive license however that should be no issue
here (as the audio crate uses the GPL)

Release Notes:

- N/A
