material: add internal layer filter getters

Browse Source 
This adds internal _cogl_material_get_layer_filters and
_cogl_material_get_layer_{min,mag}_filter functions which can be used to
query the filters associated with a layer using a layer_index, as
opposed to a layer pointer. Accessing layer pointers is considered
deprecated so we need to provide layer_index based replacements.
