Add non-interactive system server benchmarks 

This allows benchmarking system server when not sitting at the device. To use
it, launch the NonInteractiveSystemServerBenchmarkActivity and then wait awhile.

The benchmark results will be available at
/sdcard/Android/data/com.android.startop.test/files/benchmark.csv

## NonInteractiveSystemServerBenchmark



This activity is for running microbenchmarks from the command line. Run as follows:



   adb shell am start -W -n com.android.startop.test .NonInteractiveSystemServerBenchmarkActivity



It takes awhile (and there's currently no automated way to make sure it's done),

but when it finishes, you can get the results like this:



    adb shell cat /sdcard/Android/data/com.android.startop.test/files/benchmark.csv
