Use config introspection to get all entitlements

[EvanBacon]

Checklist

• I've added an entry to CHANGELOG.md if necessary.

Why

Enable auto capabilities for managed EAS projects by introspecting the app config. Introspection is a new config plugin feature which evaluates a subset of modifiers without persisting the results. This enables us to get the full results of the entitlements object.

(also slipped in a few assert fixes)

Test Plan

Using the following app.json in a managed EAS project should enable Push Notifications, Sign In with Apple, Associated Domains.

{
  "expo": {
    "ios": {
      "usesAppleSignIn": true,
      "associatedDomains": ["applinks:foobar"],
    }
  }
}

And you should see something like:

✔ Bundle identifier registered com.bacon.yolo24
✔ Synced capabilities: Enabled: Associated Domains, Sign In with Apple

Removing the values should show something like this:

✔ Synced capabilities: Disabled: Sign In with Apple, Associated Domains

Visiting the Apple developer portal for the bundle ID should show the expected capabilities https://developer.apple.com/account/resources/identifiers/bundleId/edit/XXXXXX
