Finishes [CSDK-451].
This new small public API allows users to quickly figure out if
everything in the SDK is correctly configured in a simple way:
```swift
let diagnostics = PurchasesDiagnostics.default
do {
try await diagnostics.testSDKHealth()
} catch {
print(error)
}
```
The specific underlying errors will provide information about what
failed.
We can continue growing this to check for more specific things, but for
now it does 4 things:
- Verify API connectivity: networking issues, firewalling, etc.
- Verify API key is correct
- Verify `Offerings` are configured correctly
- Verify that all products in `Offerings` are configured correctly and
found in `StoreKit`
This new API is covered by:
- API testers
- Unit tests
- Integration tests (both on `SK1` and `SK2`)
_I've taken the "shortcut" of making this `async` only (while still
compatible with Objective-C), which means it's not compatible with iOS
12.x. But that made the implementation a lot simpler, which I think is a
useful tradeoff._
