apn: Update T-Mobile NL

MCC: 204
MNC: 16, 20

* Take FP4 as baseline
* Drop MMS APN from FP3 config -- not supported anymore on the network.
* Add IMS config -- not officially supported on FP3, but accessible as
  opt-in for users. So get valid APN in for that as well.
* Take over new APN for type 'ia' from AOSP
* Drop entries for 204,20 -- not listed (anymore) in specs
