## Summary
This PR introduces a faster version of the `addProperties` function.
This new function is basically the `diffProperties` with `prevProps` set
to `null`, propagated constants, and all the unreachable code paths
collapsed.

I've tested this change with [the benchmark
app](https://github.com/react-native-community/RNNewArchitectureApp/tree/new-architecture-benchmarks)
