Initial commit of the test code for ART Service

This CL adds the scaffolding for testing the ART Tools and ART Service
libraries.

The command `atest ArtServiceTest` will fail with Tradefed errors, but
these same errors are generated by existing tests such as `atest
android-icu4j-tests`.

Test: m test-art-host-gtest && atest ArtServiceTest
