Update Date.prototype.toLocaleString for Android and Opera for Android

On https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleString

Notice that Firefox Android is marked as having no support for locales or options. However, testing http://jsbin.com/hovucawibe/edit?html,js,output on Firefox Android 60.0, which outputs the result of:

new Date().toLocaleString('en-us', { timeZone: 'America/New_York' })

produces the expected result.

I'd open a PR but I don't actually know which version of Firefox Android added support.

It should be Firefox for Android 56, because this likely depends on the Intl API which was enabled in 56: https://bugzilla.mozilla.org/show_bug.cgi?id=1344625

Can you open the PR that changes these to 56? Thank you :)

The information for normal Android and Opera for Android looks odd to me in that table, so let’s needinfo?⁠(@jpmedley) and keep this open for fixing Date.prototype.toLocaleString support information for all browsers.
