Revert "config: Remove X.509 options"

This reverts commit bb1f701212.

* include/mbedtls/check_config.h:
    * MBEDTLS_X509_RSASSA_PSS_SUPPORT: there has been an addition (of
      MBEDTLS_SHA512_NO_SHA384) at the place where it was removed.
      Re-add it before MBEDTLS_SHA512_NO_SHA384 to keep it grouped
      with MBEDTLS_RSA_C.

Conflicts:
* scripts/config.pl: this file has been replaced by config.py. Port
  the reversed changes to config.py:
    * Revert removing three symbols from the list of symbols to
      exclude from full.
