e_client: Appy base output resolution to subsurfaces

This patch is to apply base output resolution of toplevel window to all
subsurfaces. So, it removes call to e_comp_wl_hook_del() and continue to
listen E_COMP_WL_HOOK_SUBSURFACE_CREATE hook point.

Some wayland clients repeatedly reuse wl_surface to create wl_subsurface
with a different parent from previous one. The problem is that the
subsurface can't get applied with base output resolution of a new
toplevel window in this case.

To apply base output resolution of a new parent to all associated
sub-surfaces, we should call e_client_transform_core_update() for a
toplevel window whenever a subsurface gets created with a new parent.

Since e_client_transform_core_update() recursively updates transform for
all sub-surfaces, calling e_client_transform_core_update() for a
toplevel window should also update transform for all subsurfaces.
