Summary:
Adds a new framebuffer implementation, which uses xdg-desktop-portal to support remote
desktop on Wayland and uses PipeWire to deliver the screen content. So far only mouse
support is implemented, because keyboard support is missing on KWin side.

Previously used x11 plugin does not compile with Qt5, because Qt5 does
not use Xlib, it uses xcb. Rewrite screen capture plugin from Xlib to
xcb.
I made xcb libs compile required dependency, but availability of X
shared memory extension is checked at runtime. It is used to effectively
get image pixels data, instead of transfering 8Mb over the wire. Xdamage
is used to limit image getting operations only within actually changed
rectangles of screen.
BUG: 377998
Tested on single-monitor system and dual-monitor, where primary monitor
does not start at (0,0) coordinate. Image transfer works fine.
Dual-monitor only has problems with receiving mouse cursor position and
clicks, but this should be fixed outside of framebuffer plugin.

- Currently there is no configuration UI, so you have to edit the krfbrc by hand to select the framebuffer plugin to use. This will be fixed later.
- Framebuffers are shared, so that when krfb supports having mutliple servers running, the framebuffer can be shared between them (when appropriate) for better performance.
- Currently defaults to the X11 framebuffer, since this is what was hardcoded before.
