feat(firebase_messaging, android)!: android 13 notifications permission request

[russellwheatley]

Description

PR checks if the app is running on android 13 and will check the app notification permissions. If none set or permissions not granted, a dialog box will appear requesting user notification permission.

I consider this a breaking change as there is certain configuration required such as targetSdkVersion & compileSdkVersion targeting android API 33.

Users will also need to have the android:exported="true" property set in app manifest on apps running on android 12 or higher.

@russellwheatley According to msackman's comment, I think we also need to update getPermissions() method to check for:

final boolean areNotificationsEnabled = ContextHolder.getApplicationContext().checkSelfPermission(Manifest.permission.POST_NOTIFICATIONS) == PackageManager.PERMISSION_GRANTED;

@MarcinusX That makes sense. I'll update the PR 👍

We should probably mention this in the changelog for this PR

We can manually edit this when doing the next release I guess 🤔
