[ATF integration] #1 Basic ATF framework that compiles

All the minimum deps required for compiling ATF.

It generates layout-validator.jar in output that's ready for
use in studio.

Turned out we don't need to be integrated with Bridge at all.
In .iml it's still included so we can test it locally.
