e_client: add e_client_layer_set() for the change of client layer

evas_object_layer_set is used for change client layer or effect
to distinguish the usage and reduce inappropriate use, added
NEW API: e_client_layer_set

allowd layer set from E_LAYER_CLIENT_DESKTOP to E_LAYER_CLIENT_CURSOR
this api saves layer to ec->layer when in pending or block state
so the layer can be set after pending or block is free.
