xwayland: pass the emulated mode by reference 

When using xrandr emulation, the emulated mode is passed as a pointer to
the XRandR mode from the xwl_output associated with the X11 client.

In preparation for fullscreen mode, we want to be able to reuse that
code but use a separate emulated mode.

Simply change the internal API to pass a reference to the emulated mode.

This introduces no functional change.
