CryptoPkg: Update process_files.pl to automatically add PCD config option

Recommend from Gerd:
(2) Keep the EC config option, but update process_files.pl to
  automatically add the PcdEcEnabled config option handling
  to the files it generates.

When remove 'no-ec' from openssl configure list, will automatically remove
'OPENSSL_NO_EC', 'OPENSSL_NO_ECDH', 'OPENSSL_NO_ECDSA', 'OPENSSL_NO_TLS1_3',
form header, and add '/ec/.', '/sm2/.' files to INF files.
