kmsdrm: Allow windows to be marked as "unfocusable".

Browse Source 
In this case, it means a newly-created window on a specific display won't
get mouse/keyboard input (which, presumably, will continue to go to a window
on a different physical display instead).

This also makes SDL_SetWindowFocusable() functional on the kmsdrm backend, to
change this flag later, but to be clear, there are no window focus events to
jump between displays in this backend, so this is only useful to manually
tweak things later.

Fixes #14289.
