Cross-desktop approach to moving the cursor remotely on wayland. Should
work on X11 too, so we can consider drop the other one as well.
It adds support for receiving full text as well, which didn't use to be
possible.
Summary:
Windows no longer needs a separate plugin, and X11 and Wayland are now in
separate files instead of having lots of ifdefs.
Test Plan: Tested on X11, Wayland and Windows.
