Use an enum to represent screen orientation in the Project Settings

- Tweak the setting property hint to be more informative.
- Make the setting a "basic" setting so it appears when Advanced Settings
  is disabled.
- Remove redundant orientation setting in the iOS export preset.
  The project setting is now used (like on Android).

Projects upgrading from a previous version will have to set the
screen orientation again in the Project Settings if it wasn't set
to the default value ("landscape").
