Attest: Implement get token size API

Extend the attestation API with the implementation of
psa_initial_attest_get_token_size() function. It is
meant for retrieving the exact size of the initial
attestation token, but current version just returns
a hard coded value.

Replacement of handwritten veneers to the auto-generated
veneers.
