[Feature Request] Clarify methods referenced in parent

Sometimes a parent class, interface or namespace provides a method that can be, or has to be overridden in the implementation. For example when using [`Form`](https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.form?view=windowsdesktop-6.0)s with the [`PreFilterMessage`](https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.imessagefilter.prefiltermessage?view=windowsdesktop-6.0) method from [`IMessageFilter`](https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.imessagefilter?view=windowsdesktop-6.0) to prevent illegal or unwanted input.
Currently, functions like these show up highlighted as a referenced method, but Code Lens reports 0 references which looks quite confusing to me.

Proposal:
Add some sort of identifier that shows it's inherited like `0 references | inherited` or `0 references | IMessageFilter`
