Revert "pipewire capturer: Reduce the amount of copying"

This reverts commit 8856410b6d54b546bdb3185587474f0f9b3a7c2e.

Reason for revert: chromium:1447540

Original change's description:
> pipewire capturer: Reduce the amount of copying
>
> Improves the capture latency by reducing the amount of
> copying needed from the frame. We keep track of the
> damaged region of previous frame and union it with
> the damaged region of this frame and only copy this
> union of the frame over. X11 capturer already has
> such synchronization in place.
>
> The change is beneficial especially when there are
> small changes on the screen (e.g. clock ticking).
> For a 4k screen with 128 cores, I observed the
> capture latencies drop from 5 - 8 ms to 0 ms when the
> system is left idle. This is in line with the X11
> capturer.
