wayland: handle runtime hidpi-window-scale changes correctly 

Semi-regression although this option never really did what the manual
said until recently. In the past, this option also controlled whether or
not mpv set the wayland buffer_scale to the value of the wl_output or
force it 1. This had varying effects depending on the exact compositor
configuration. That logic has now all been removed and this option now
only controls whether or not to scale the window with the hidpi scale
factor we get from the compositor. i.e. it actually does what the
manual says now.
