Keep module compatibility with mbedtls 2.x (old LTS branch). A patch has been added to allow compiling after removing all the `psa_*` files from the library folder (will look into upstreaming it). Note: mbedTLS 3.6 finally enabled TLSv1.3 by default, but it requires some module changes, and to enable PSA crypto (new "standard" API specification), so it might be best done in a separate commit/PR.
