fix(useAdjacentOverloadSignatures): don't report #private and public members with same name

[Conaclos]

Summary

Fix #3309
I introduced a new enum ClassMemberName that is returned by AnyJsClassMemberName::name.
This allows to carry the information if the name was #private or public.
I had to refactor the code of useAdjacentOverloadSignatures to accommodate with this change.

I also fixed noMisleadingInstantiator that previously reported class C { #new(): C {} }.

Test Plan

I added tests.
