CMake: Allow evaluating features before a module is processed

Introduce an internal qt_feature_evaluate_features() function
which takes a list of configure.cmake paths, and evaluates the
features declared in those files, thus setting a bunch of cache
variables.

This is required to implement the equivalent of what qtbase/src.pro
does, which includes the feature .pri files to decide whether
bundled 3rd party libraries need to be built.
