cocoa-cb: add logging for CGL pixel format attributes

Browse Source 
depending on the capabilities of the system and testing of various
attributes the resulting CGL pixel format can change. due to that
probing it can be helpful to know which pixel format is used to create
the CGL context. added some verbose logging that outputs final pixel
format.
