- create JavaTypeSubstitutor as a mirror for PsiSubstitutor
- copy-paste MethodSignatureUtil.areSignaturesErasureEqual() and migrate it to
JavaTypeSubstitutor
- use a pair of method and substitutor instead of
'MethodSignatureBackedByPsiMethod'
- add JavaClass.getDefaultType() which goes into JavaPsiFacade and creates an
unsubstituted PsiClassType for the class
- green code
The only PSI usage left is TypeConversionUtil.erasure(), which needs to be
copied and migrated somehow
