Allow commands with user-defined names to be hidden from cmdpal #7179
Description
Currently we can return an empty string from GenerateName() in order to hide a command from the cmdpal, but if a user decides to explicitly give their command a name, it'll show up because it doesn't hit GenerateName(). There's no smooth way to hide the command in this case. This is really just to appease the ATS's (#6732) very minor desire to hide anchor mode from the cmdpal because the use case doesn't really make much sense.
