[Form] Support customized intl php.ini settings 
`IntlDateParser->parse()` behaves differently when `intl.error_level` and/or `intl.use_exceptions` are not 0.

This change makes sure `\IntlException` is caught when `intl.use_exceptions` is 1 and warnings thrown when `intl.error_level` is not 0 are ignored.
