xdg: add missing tracking of configure serials

Browse source 
In some cases, we would schedule a configure event but not record that
we had done so, leaving view->pending_configure_serial incorrect. This
caused incorrect handling of in-flight commits that had not yet taken
the new configure into account, such as assuming that the client had
ignored the configured size and incorrectly resetting view->pending.

Fixes: #2774
