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

This reverts commit f2177f6612079ccce9c320ea7e77bc934c684f5c.

Reason for revert: Broke WebRTC to Chrome rolls:
https://chromium-review.googlesource.com/c/chromium/src/+/3135220
example: https://ci.chromium.org/ui/p/chromium/builders/try/fuchsia-x64-cast/431230/overview

ERROR at //third_party/webrtc/modules/desktop_capture/linux/egl_dmabuf.cc:26:11: Include not allowed.
#include "rtc_base/sanitizer.h"
          ^-------------------
It is not in any dependency of
  //third_party/webrtc/modules/desktop_capture:desktop_capture_generic
The include file is in the target(s):
  //third_party/webrtc/rtc_base:sanitizer
which should somehow be reachable.



Original change's description:
> PipeWire capturer: implement proper DMA-BUFs support
>
> 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.
>
> Documentation for this behavior can be found here:
> https://gitlab.freedesktop.org/pipewire/pipewire/-/blob/master/doc/dma-buf.dox
