873ef0e230 libandroidfw_tests: package test data correctly 
- Convert to use soong, which allows bundling test data with benchmarks.
- Also separate libandroidfw_benchmarks so that it doesn't depend
on gtest.

Test: manual

Benchmarks on bullhead-userdebug show that there is a negligent
performance impact when using sparse entries on a 30% loaded
sparse type of 1000 resources.
