e_comp_object: introduce e_comp_object_render_update_lock/unlock

if e_comp_object_render_update_lock is called, enlightenment does not
update evas image object in job callback of compositing(_e_comp_cb_update)
until render_update_lock count is decreased zero.

this api does not prevent updating evas image object when
e_comp_object_dirty is directly called.
