Add properties enabled_features and disabled_features the respective
library targets.
This makes it possible to query the enabled classes in dependent libraries
(for example, Qt for Python).
Add a test verifying whether the Open GL configuration is reflected
correctly in the feature properties to the existing test_opengl_lib
autotest.
