This adds a basic unit test to check USD has been correctly build with imaging components to support building both with the old and new libs, it automatically adds the test when it detects a library with imaging enabled. (platform devs will have to pay attention it runs the test to validate the libs build correctly) For future use in the code it also defines a USD_HAS_IMAGING define one could check if we're building against an USD lib that has it (just because we build/ship with it, doesn't mean downstream builds will ship with it, so we'll have to be a little pro-active there) Reviewed By: sybren Differential Revision:https://developer.blender.org/D14456
