Revert "Reland "PipeWire capturer: implement proper DMA-BUFs support"""

This reverts commit 677195d3eb6a5f0bc1d31d794a5190ba281c0335.

Reason for revert: Broke WebRTC to Chrome rolls:
https://crrev.com/c/3141000
example: https://ci.chromium.org/ui/p/chromium/builders/try/linux-rel/790256/overview
The error is similar to the failure on previous attempt to land this CL. See: https://crrev.com/c/3135220, and crash https://ci.chromium.org/ui/p/chromium/builders/try/linux-rel/787945/overview

> > Currently both KWin (KDE) and Mutter (GNOME) window managers don't
> > use DMA-BUFs by default, but only when client asks specifically for
> > them (KWin) or when experimental DMA-BUF support is enabled (Mutter).
> > While current implementation works just fine on integrated graphics
> > cards, it causes issues on dedicated GPUs (AMD and NVidia) where the
> > code either crashes or screensharing is slow and unusable.
> >
> > To fix this, DMA-BUFs has to be opened using OpenGL context and not
> > being directly mmaped(). This implementation requires to use DMA-BUF
> > modifiers, as they are now mandatory for DMA-BUFs usage.
