ci: Fix unit test failures

- protocomm: Fix leakage due to ECDH context not being
             initialised and freed properly
- mbedtls (RSA): Added mandatory RNG parameter wherever required
                 Disabled `test performance RSA key operations` UT
- mbedtls (AES_GCM): Added mbedtls_gcm_update_ad() wherever required
                     for updating associated data
- unit_test_app: Fix build issue when heap tracing is enabled
