xwayland: Check emulation on client toplevel resize

Browse Source 
When a reparented window is resized directly check the emulation instead of
doing this only when the window manager parent window is resized, what might
never happen.

For that to work we need to make sure that we compare the current size of the
client toplevel when looking for an emulated mode.

Changes by Hans de Goede:
- Remove xwl_window x, y, width and height members as those are no longer used.
- Add check for xwl_window_from_window() returning NULL.
