Scale Workaround for legacy high-res displays

[ghost]

Bug Report

Requesting a workaround for two head units with high-resolution displays that don't support scale values. The reason is per user complaints but also (and more importantly) these displays won't meet driver distraction guidelines for SDL navigation apps. With "pixel density and scale" API the workaround is rather small allowing these head units to increase the appearance of the app UI elements.

Reproduction Steps

1. Start an IVI (see below affected 10" IVIs)
2. Register an SDL application with NAVIGATION HMI type
3. Start the application on the IVI

Expected Behavior

• App UI should be of decent size.
• Button size should be big enough to hit.
• App performance should be decent.

Observed Behavior

• The app UI is very small.
• Buttons are hard to hit.
• Framerate is very low

OS & Version Information

• Android Version: Irrelevant
• SDL Android Version: 4.10.1
• Testing Against: Ford Explorer 10" portrait or Lincoln Navigator 10" landscape

Test Case, Sample Code, and / or Example App

There is an issue and a PR in sdl_ios see smartdevicelink/sdl_ios#1567 and smartdevicelink/sdl_ios#1568 that add the workaround for Ford and Lincol only and only if width or height is > 800. The workaround fakes a scale of 1.33333 upon RAI response.
