[New] jsx-no-target-blank: Improve fixer with option allowReferrer

[apepper]

If you do not support Internet Explorer (any version), Chrome < 49, Opera < 36, Firefox < 52, desktop Safari < 10.1 or iOS Safari < 10.3, you may set allowReferrer to true, keep the HTTP Referer header and only add rel="noopener" to your links.

Source: https://github.com/yannickcr/eslint-plugin-react/blob/master/docs/rules/jsx-no-target-blank.md#when-to-override-it

This PR improves the fixer to use rel="noopener" if allowReferrer is set.
