wayland: further xdg-decoration/border refinements

Browse Source 
The value of the border option should always match what the actual state
of the window is. Previously if a compositor rejected the request by
mpv, it did not correct itself. Also add some code to keep track of
decoration requests. Anytime the state is changed, make the last saved
request again (doesn't hurt and seems like intuitive behavior).
Unfortunately, this isn't foolproof since options only send callback if
the value is changed. (ex. on sway if the floating window has no border,
and then is titled, setting the border value to "yes" does nothing since
tiling the window already set the border value to "yes").
