OTP-7452 Support for SQL_WCHAR, SQL_WVARCHAR and strings as binaries

ODBC now handles the types SQL_WCHAR and SQL_WVARCHAR. ODBC also has a new
connection option to return all strings as binaries and also expect strings
to be binaries in the param_query function. This provides some but not a
full unicode support.
