Prepare SDK for KLP MR1. Do not merge.

System images are in 19 rev 2 for MR1 (since they have minor.major)

platform-tools: update the API diff file that lint uses (not automated yet.)
build-tools: llvm-rs-cc issue affecting RS NDK mode in Gradle.

Note that support is set to 19.0.1 which means it will have to be
released using the new addon.xsd format that allows extras to have a
major.micro.minor format. That will be an interesting way to test this
feature.

Add API demo for game style system UI interaction.

Shows the ideal way for a game to interact with system UI, hiding
the status bar and nav bar while being played, making them visible
when paused or otherwise interacting with controls of the game,
and determing layout of game controls to not be covered by the
status bar or nav bar.
