Vlad Zahorodnii dbee0573c4 Lock clientStepUserMovedResized to move resize geometry changes
On Wayland, the move resize geometry and the frame geometry are
completely out of sync.

This change synchronizes emitting of the clientStepUserMovedResized
signal to the move resize geometry changes.

It simplifies code of InternalClient and XdgSurfaceClient, and makes
adding support for other shell surface protocols easier as there's less
boilerplate stuff that you would need to take care of.
