[RFC weston v2] libweston: Commit subsurfaces before committing root surface

[Philipp Kerling]

Committing the root surface triggers a commit of the xdg_surface state,
which might require the subsurface state already being applied (e.g.
when an xdg_toplevel needs to follow size constraints, the subsurfaces
must be in the right position and size at the time this is verified).
