Firebase-js-sdk: FR: Sign in with Apple Support

[jacobg]

Add support for authenticating with Sign in with Apple. With the release of iOS 13, Apple will require that you implement this to be listed on the App Store if your App uses other 3rd party login providers.

Sign In with Apple will be available for beta testing this summer. It will be required as an option for users in apps that support third-party sign-in when it is commercially available later this year.

There is already an open issue and PR in the Firebase iOS SDK for Sign In With Apple Support, but hybrid apps (e.g., Cordova) will also need this support in the JS SDK.

In addition to hybrid apps, IMO this makes sense to add as another available provider for use in any web application.
