Description

### Description

This issue follows that one https://github.com/lowRISC/opentitan/issues/21708 where the main parts of the feature has been tested via this PR https://github.com/lowRISC/opentitan/pull/23116. Nevertheless, this PR also indicates that there are still some missing things to be added:
- [ ] Verify context B with multi-streamed (= different context switching)
- [ ] Remove msg_length check from the hmac_base_vseq as should be part of the SCB
~~- [ ] Verify intermediate digest when switching~~ crossed out as this will be covered by #23240

FYI @gdessouky @andreaskurth @ballifatih : and if you feel that anything else as to be tested, please rise it here.
