Include Android Samples to Dawn

Adding three sample Android Applications that use Dawn:
1. Render HelloTriangle using C API
2. Render HelloTriangle using C++ API
3. Compute Sample using C++ API

Follow "Building Instructions for Android Application Samples" in
go/dawn-on-android-samples to test the samples locally.
