x11/window: Ensure we send a ConfigureNotify to just mapped windows

Browse Source 
When managing a non-OR window we're required by the ICCCM to behave as
if we received a ConfigureRequest which means that we must generate a
synthetic ConfigureNotify even if the window isn't moved or resized
from its current (initial) geometry.

During MetaWindow's x11/wayland split a slight behavior change for x11
windows crept in. Before the code split, MetaWindow->rect was
initialized with the X window's geometry, but now we're not
initializing MetaWindowX11Private->client_rect which causes the checks
for whether it's necessary to move/resize the window in
meta_window_x11_move_resize_internal() to tell us that we do need to
move/resize which means we do an XConfigureWindow() call and don't
send the sythetic ConfigureNotify. But since the X window isn't really
moving, the XConfigureWindow() call doesn't cause the X server to
generate a ConfigureNotify which breaks some clients such as Java's
AWT.

We can fix this by setting MetaWindowX11Privatew->client_rect for both
OR and non-OR windows. We can set buffer_rect for non-OR windows as
well to simplify the code since it will be assigned the correct value
in meta_window_x11_move_resize_internal() .
