Deprecate forceName Component APIs, Transform (#2987)

Deprecate forceName APIs on components.  These are only supported on
modules/instances in the MFC.  (This could be revived in the future if
desired.)

Deprecate the ForceNamesTransform.  This doesn't need to be public given
that the forceName Chisel API is available to users.
