Explicitly pass the list of tests as LOCAL_ROBOTEST_FILES, and support sharding the list of tests into multiple test runners. Also filter out BaseRobolectricTest.java, which covers the only use of LOCAL_ROBOTEST_FILES in Android.mk files. Bug: 133878985 Test: m RunSettingsLibRoboTests runs the same number of tests before and after Test: m RunSettingsLibRoboTests runs the same number of tests when sharded Change-Id: Id85ffe03c98e722303eaa6def17812ed2244c6a6 Merged-In: Id85ffe03c98e722303eaa6def17812ed2244c6a6
