qwaylandwindow-Short-circuit-isExposed: qtwayland resize fix

An initial configure event does make qtwayland to send a window geometry
with the initial values, just that it doesn't take into account new
resizes which are required when starting before the shell.

+Subject: [PATCH] qwaylandwindow: Short-circuit isExposed()
+
+This patch short-circuits isExposed() to allow sending
+xdg_shell:set_window_geometry() when re-sizing the window.
+
+isExposed() depends on mFrameCallbackTimedOut begin set-up, which takes
+precedence on checking isExposed() from mShellSurface.
+
+As such, this patch allows to take into consideration the fact that
+geometry did indeed changed and requires sending a new
+set_window_geometry() request, in order to to avoid a protocol error as
+the compositor already geometry provided by the client instead of
+computing one for itself, so we need to send a new set_window_geometry()
+with newer dimensions.
