Dmitry Rykun 45ba0425e7 Event name normalization (#42586)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/42586

Every event name must be normalized.

The normalization strategy is:
1. If it starts with `top` -> do nothing.
2. If it starts with `on` -> replace `on` with `top`.
3. Else -> capitalize the first character and prepend `top`.

We have it for the old renderer on iOS [here](https://github.com/facebook/react-native/blob/a7586947d719a9cd2344ad346d271e7ca900de87/packages/react-native/React/Base/RCTEventDispatcher.m#L12-L21). This one is also used by the interop layer.
Static ViewConfigs being a part of the new renderer [replicate](https://github.com/facebook/react-native/blob/a7586947d719a9cd2344ad346d271e7ca900de87/packages/react-native-codegen/src/generators/components/GenerateViewConfigJs.js#L164-L172) this behavior to match the old rendered.

The Android that we have is incomplete, it is missing the [*2. If it starts with `on` -> replace `on` with `top`*]. This means that some events names that worked with the old renderer would not be compatible with the new renderer + Static ViewConfigs. Specifically every event names that start with `on`.

This diff implements event name normalization on Android.

Changelog: [Internal] - Update event normalization algorithm to match SVCs.
