xdg_shell: allow views to change geometry anytime 

Currently, when sway sends a configure with some geometry and the
client responds with a different geometry in a commit that acks that
configure, sway ignores the new size. Sway applies the surface
geometry it had requested to the container, not what was actually
committed, in the following transaction.

This change allows any client commit to change its surface geometry,
even if it is a response to a configure event.
