wayland/vulkancontext: Sync surface state before vkQueuePresentKHR

A side effect of vkQueuePresentKHR is the Vulkan implementation calling
wl_surface_commit() on the corresponding Wayland surface. Thus, before
this, we must synchronize the surface state (e.g. opaque region, window
geometry, etc) that changed since last time. Prior to this commit this
was done after calling vkQueuePresentKHR(), causing the surface state to
always correspond to the previous buffer state. As of this commit this
is now done before calling vkQueuePresentKHR(), thus before
wl_surface_commit().
