[quartz] implementing release_source_image (#11059)

Browse source 
The image surface that _cairo_quartz_surface_acquire_source_image creates never
seems to be released, probably because there is no release_source_image callback
in the quartz code.

The attached patch fixes that problem, at least insofar as the image surface
itself is no longer leaking.  I'm not sure whether any other cleanup needs to
happen here.
