Reland "Add an optional override for AudioRecord device"

Browse Source 
This is a reland of 1b8ef63876ebfa55a51c8ca9b1d8206bf8233e01. It was
previously reverted (https://webrtc-review.googlesource.com/c/src/+/175008)
but the revert was found to be unnecessary.

Original change's description:
> Add an optional override for AudioRecord device
>
> This is important when we have multiple named devices connected over
> USB (eg. "Webcam", "Microphone", "Headset") and there is some way to
> choose a specific input device to route from.
>
