Remove the native delta client from Android

Summary: This was an experiment to patch individual deltas in development instead of reloading the whole JS bundle. With improvements such as Fast Refresh that reduces the need for reloads and bundle splitting that reduces the number of modules and memory by 10x, we won't be needing this complex optimization that we never properly made work. This diff removes that code and I will be removing the JS side of things in Metro in a follow-up diff.
