Feat/private symbols (dotnet#9972)

* (fix): when specifying "includePrivateMembers":"true" in the docfx.json file, enumerates all the private members of the classes.

Todo:
- remove class constructor;
- remove compiler generated members.

* Removes class constructors and compiler generated members.

* - Use a named parameter to specify the import options.
- Refactoring the parameter to directly pass a boolean value.
