Revert "Reland "Reland "Reland "Implemented screen enumeration and selection for desktop capture under X11 using the X Resize and Rotate extension version 1.5.""""
This reverts commit 703a5d76d9ba8e7984509cc7bf70fb4ed84ef6be.
Reason for revert: Breaks a downstream project. I will notify when it is possible to reland.
