_multitexture_quad_single_primitive: avoid wrap overrides
_multitexture_quad_single_primitive: avoid wrap overrides

This avoids using the wrap mode overrides mechanism to implement
_cogl_multitexture_quad_single_primitive which requires memsetting a
fairly large array. This updates it to use cogl_pipeline_foreach_layer()
and we now derive an override_material to handle changes to the wrap
modes instead of using the CoglPipelineWrapModeOverrides.
