Remove PDM::SetProfiles..()

Prior CLs have removed all usages of this function, so it can finally
be deleted! See go/pdm-autofill-table-interface why this function
shouldn't exist in it's current form.

This removes the final usage of enforced profile additions, which are
also removed by this CL.

One usage of enforced profile updates (RecordUseOf()) still exists. A
follow-up CL will remove that too, before the queuing mechanism can
be simplified further.

This removal saves ~1k of binary size.
