window/wayland: Always include a size when sending a configuration

Browse Source 
Prior to 67033b0a mutter was accidentally including sizes for
configurations that were just focus state changes. This was not leading
to any known problems on the client side, but it was causing issues in
mutter itself when detecting whether a resize originated from the client
or the server.

Not including sizes in focus change configurations anymore however
revealed a bug in gtk. It was storing the window size when in a fixed
size mode (tiled/maximized/fullscreen), but not on any other server side
resizes. It was then restoring this stored size whenever there was a new
configuration without a size while in floating mode, i.e. the focus
change configurations generated by mutter after 67033b0a.

This change now addresses the issue 67033b0a was fixing in a way that
restores the previous behavior of always including the size whenever
sending a configuration.
