[PATCH weston] desktop-shell: Set surface resizing state during interactive resize

[Philipp Kerling]

xdg_shell requires this information to be shared with the client in
order to conform with the specification.

The code to forward this to the client by way of a configure() event
is already in place and works fine, it was just never being used until
now.
