Make *Context.Config return a Config instead of a interface{}
In Soong, a Config() method will always return a Config. Make
ModuleContext, SingletonContext, TopDownMutatorContext and
BottomUpMutatorContext's Config() methods explictly return
a Config to avoid having to type-assert everywhere. Overriding
the Config method requires duplicating the list of methods in
blueprint.BaseModuleContext and blueprint.BottomUpMutatorContext,
following the same pattern used by the other *Contexts.
Config() obsoletes the AConfig() method used in some places, which
will be cleaned up in the next patch.
