Make manager required in AstroidBuilder/InspectBuilder

ChangeLog

@@ -10,6 +10,8 @@ Release date: TBA
 * Removed internal functions ``infer_numpy_member``, ``name_looks_like_numpy_member``, and
   ``attribute_looks_like_numpy_member`` from ``astroid.brain.brain_numpy_utils``.
 
+* To alleviate circular imports, the ``manager`` argument to ``AstroidBuilder()`` is now required.
+
 * Constants now have a parent of ``nodes.SYNTHETIC_ROOT``.
 
 * Fix crashes with large positive and negative list multipliers.
