 [ACTION] [#7765](https://github.com/Mbed-TLS/mbedtls/issues/7765) Implement `mbedtls_ecdsa_raw_to_der` and `mbedtls_ecdsa_der_to_raw` as described below.
 
 ```

-                             unsigned char *der, size_t der_size, size_t *der_len,
-                             size_t bits);

-                             unsigned char *raw, size_t raw_size, size_t *raw_len,
-                             size_t bits);
