compositor: Remove the edges parameter from send_configure

send_configure was originally modelled after
wl_shell_surface::send_configure, which takes these arguments. However,
the X WM and xdg_surface::configure variants don't use these arguments.

We already store the resize edges for a surface while it's being
resized, so just use the saved state in the wl_shell_surface variant.
