Revert "[M123] [Audio] Propagate socket errors to sinks and sources. Prevent reuse."

This reverts commit 0105c8e541581f18d0a7f6e3a8d629f917385550.

Reason for revert: Exposing latent threading issues in audio input device users and not need in 123 since https://chromium-review.googlesource.com/c/chromium/src/+/5354149 was reverted.

Original change's description:
> [M123] [Audio] Propagate socket errors to sinks and sources. Prevent reuse.
>
> M123: This drops AudioInputDevice and AudioOutputDevice tests which had
> merge conflicts.
>
> If the browser side closes the socket the renderer is only notified
> through a failure to read from the socket. This error was being dropped
> instead of propagated to the RenderCallback and CaptureCallback.
>
> This error signal is then used to prevent reuse of AudioRendererMixer
> instances. This fixes the linked issue (same-origin navigations where
> the mixer is reused between navigations).
>
> There may still be constructions where a RenderFrame which creates a
> shared sink is closed while the sink is being used. I haven't yet been
> able to construct such a scenario though.
>
> Bug: 326903566
>
> (cherry picked from commit 7c882251cf9d4f6fe2b212084674f1ab62897fea)
