Revert "Improve screen sharing with PipeWire on Wayland"
This reverts commit 84524e6b196153e35910111f61c36489ec2bd1d7.
Reason for revert: https://webrtc-review.googlesource.com/c/src/+/160649/33#message-a83e8959e03a274642ca2ce1abb9ea0099f08097 + suspected in breaking WebRTC to Chromium rolls https://chromium-review.googlesource.com/c/chromium/src/+/2468139
Original change's description:
> Improve screen sharing with PipeWire on Wayland
>
> Currently, sharing a screen or a window on Wayland opens unnecessary
> preview dialog on Chromium side, which is then followed by a similar
> dialog on xdg-desktop-portal side. The Chromium dialog is useless on
> Wayland, as it doesn't show anything. This is because Chromium doesn't
> have access to screen content as in case of X11 session. To fix this, we
> want to avoid showing the preview dialog in case we find that we run on
> Wayland and only pick a screen or a window from the dialog that comes
> from xdg-desktop-portal.
>
> This patch splits BaseCapturerPipeWire class, moving portal related code
> into XdgPortalBase, which does all the DBus communication and which is
> supposed to be reused by BaseCapturerPipeWire when the user confirms
> the dialog from xdg-desktop-portal. The XdgPortalBase is extended to
> support multiple calls at once, where each call is identified by Id.
>
> Relevant change on Chromium side will be in a different review.
>
