Suggested enhancement

Per suggestion from @paul-elliott-arm, open a separate issue here to track the ones discussed in global variable issue in PSA crypto.

  • We may need synchronization between our libraries, otherwise we may run into thread-safety issues when we call psa_crypto_init from different threads.

Justification

Mbed TLS needs this because

This is a subset of #3263, but it doesn't call out psa_crypto_init explicitly, only functions that access keys, so I'm leaving it open for now.

Note that per our roadmap, we intend to make the PSA subsystem thread safe by the end of 2024.
