Allows modsuits to be set to wear on other slots. (#66667)

Allows for MODsuit control units to be worn on slots that isn't the bag slot and actually work.
So far no MODsuits will actually use this, but I would like to add one in the future, I'm just not motivated to do the MODsuit itself, so I'm adding the support for it at least to see if it would be approved.

Lawyer tie modsuit will be real in 2023.

This doesn't really change the game much so I don't know how much I actually have to explain here.
