Summary:
After D8397, interfaces have the I prefix again, so the "Do" prefix on
methods with repeated names may not be needed for them in most cases.
This commit also consolidates the method_managed_name calls with the
overload receiving attributes::function_def instead of plain name.
Fixes T7791
Depends on D8645
