Add measurement command line args to SampleApp

Browse Source 
This way, we may be able to use SampleApp as a performance benchmark
tool that's closer to real-world use cases than nanobench.

For example, we can now run

./out/Release/SampleApp --slide Chart --backendTiles 8 --measureMS 2000

to test the threaded backend.
