Add key agreement negative tests

[paul-elliott-arm]

Description

Add new psa_key_agreement() functionality to both key exercises (agreement with self) and key_agreement_fail() tests. This brings its testing in line with psa_raw_key_agreement() and resolves #9513

Having to update the psa_sim generated files in this PR was unfortunate, as it showed we should have done it in previous PRs (I hadn't realised this would need to be done, and of course nothing failed at that point). Thus I have had to correct some of the previous headers in order to not have to unnecessarily add psa_key_id_t to the list of serialised classes. This will cause conflicts later unfortunately.
