e_comp_object: add e_comp_object_native_usable_get()

API e_comp_object_native_usable_get returns if cw->obj is drawable using ns
when a client attaching and committing NULL buffer, its pixmap is changed unusable
and at the same time, server make the client unmap and emit hide effect
to run hide effect, moudules can refer if a window still holds native surface
by using this api
