Introduce a faster version of the addProperties function (#28969)

## 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. ## How did you test this change? I've tested this change with [the benchmark app](https://github.com/react-native-community/RNNewArchitectureApp/tree/new-architecture-benchmarks) and got ~4.4% improvement in the view creation time.
