This change adds support for renaming methods that are referenced in nameof expressions during Inline Rename, Rename Tracking, and RenameSymbolAsync. For all of these features, there are three primary cases:

- Rename invoked from a method declaration with no overloads: Any nameof expressions that reference the method are unambiguous and are therefore updated to the new name.
- Rename invoked from a method declaration with overloads: In this case, any references in nameof expressions are renamed only if the RenameOverloads option is set to true (e.g. when the user checks the "Rename overloads" checkbox in Inline Rename).
- Rename invoked from a reference in a nameof expression: We always rename all overloads by automatically setting the RenameOverloads option to true and disabling Inline Rename's "Rename overloads" checkbox.
