Macrobenchmark tests are not supported out of the box

[dmarin]

Simple-flank does not create the flankRun test when the module is a com.android.test, so it can not be used for macrobenchmark test out of the box
https://developer.android.com/topic/performance/benchmarking/macrobenchmark-overview#setup-macrobenchmark

We can workaround by creating a custom FlankRunTask setting the flank yaml file, but, ideally the plugin would create the task also for these sort of modules.

BTW thanks a lot for the plugin, it works great! 💪
