Add automation to Android build, change PNG to PPM.

This adds libs/viewer to filament-utils-android and provides JNI bindings for AutomationEngine. This commit also changes the AutomationEngine to use PPM for screenshots rather than PNG. The reasoning is that it is wasteful to include stb and our two image-related libraries just to dump screenshots, especially for a feature we might not use on Android.
