x11: remove xinerama and refactor window geometry

Browse Source 
mpv mixes xinerama and randr usage together which gets kind of
confusing and is also pretty stupid. Xinerama is completely unneccesary
today since randr can do everything it can do and much more. Remove it.
This reworks a lot of the window/geometry handling stuff to be centered
completely around xrandr_display plus some other tweaks to the geometry
handling. An important concept is that current_icc_screen is changed
into current_screen and used more generously since it is useful for
things besides just icc profiles.
