Quit fullscreen on new x11 window

After the removal of quitfullscreen() dwl wouldn't compile widh xwayland
enabled because createnotifyx11 was still using the old function

Delete quitfullscreen()

quitfullscreen() was replicating the functionalities of setfullscreen(c,
0)

Reusing setfullscreen() in quitfullscreen() leads to a 3 line function,
which is useless since quitfullscreen() is used once anyway

Keep windows fullscreen after redraw

This fixes the bug that happens when changing workspace (or any time
arrange() is called) where there are fullscreen windows, which are still
fullscreen but leave the space for layer surfaces like waybar (which
should be hidden when going fullscreen)

Also as soon one fullscreen window is found hte function returns to
improve efficiency

Set fullscreen simpler

use m->m (fullscreen on top of layers)

Restore windows after fullscreen

Store position and size of windows before going fullscreen. This is more
efficient than arrange() and also works with floating windows

All the clients keep their original position because arrange() isn't
used after quitting fullscreen

No borders on fullscreen windows
