WIP: support workflow

Adds the ability to open up a support workflow with a single line of code, SupportView.

This is set up as a new folder within RevenueCatUI, and it reuses a lot of stuff from RevenueCat itself.

It's currently very hacky, but all the functionality that is there works correctly.

Includes:

• Open up the support workflow
• If you have an active subscription
  • if subscription is from apple, open up manage subscriptions screen
  • if not, inform them that they need to manage it elsewhere, provide a button to open up management screen of the store
• Ability to restore with a nice-looking flow
• Ability to contact support (although we need to make the actual link configurable through a backend endpoint)
• Ability to begin a refund request through apple (although we'd also want to provide extra UI there with a winback offer)
• Ability to see your current subscription, expiration, renew status, date and price
