Support trust_server_certificate option in dbconsole

ODBC Driver 18+ encrypts connections by default and validates SSL
certificates, causing `rails dbconsole` to fail against SQL Server
instances using self-signed certificates (e.g. Docker). Pass the -C
flag to sqlcmd when trust_server_certificate is set in database.yml.
