Create platformtestprotos.

This target contains some proto definitions used by TradeFed. TF will
use this instead of platformprotos to reduce proto dependencies on the
platform.

A separate build file is created so its ownership is managed separately.
The OWNERS file will be updated due to merge conflicts.
