[Feature request]: Add Enabled flag

### Is there already an issue requesting this feature?

- [x] I have searched the [existing issues](https://github.com/baseflow/flutter-permission-handler/issues).

### Please select affected platform(s)

- [ ] Android
- [x] iOS
- [ ] Windows

### Use case

I've noticed that many people have issues with enabling the post installation flags to allow access to specific permissions.

It would therefor be nice, when a Permission check would respond in the console whether the flag is set or not.

### Proposal

Some ideas i have are:

- add the 'enabled' flag to the Permission as `Permission.isEnabled` or `Permission.enabled`.
- print to the console when a permission is requested but the `enabled` value is not set
- add `PermissionStatus.disabled` as another enum (least recommended)
