Add models for many methods in javax.lang.model and com.sun.source

Summary:
This is mostly useful to authors of annotation processors and
`javac`-based static analysis tools. The nullable return models
cover these packages pretty comprehensively (with the exception
of the various visitor classes). The non-nullable parameter models
are mostly there to help make the nullable return models more useful,
as some codepaths will pass a nullable object to one of the utility
classes but never actually invoke a method on the nullable object itself.
