Summary:
Encountered this, causing typechecking to fail on an example in the current RN documentation.
`onFail` is an optional parameter (see https://github.com/facebook/react/blob/8e2bde6f2751aa6335f3cef488c05c3ea08e074a/packages/react-native-renderer/src/ReactNativeTypes.js#L106), which is not optional in current TS types. Update the TS typings to match.
Note that "?" here is positioned to be a Flow optional parameter, instead of a maybe type. Which means it accepts undefined, but not null, matching the TS usage of "?" which always means possibly undefined (but never null, like a flow maybe type allows).

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/35169
This reorganizes typing structure a bit.
`Utilities.d.ts` was originally added for utilitiy types but I ended up leaving it a grab bag of types that didn't belong to any individual bit of code. Out of what is in it right now, `Insets` was actually public, and seems to have been imported.
We also run into files around the renderer which are [currently overwritten](https://github.com/facebook/react-native/commits/e286da25fc83324363486eb668806aca179f74b3/Libraries/Renderer/implementations/ReactNativeRenderer.d.ts) by the React sync script.
Finally, all of the top-level imports of `Utilities` were auto-generated by VS Code, but fail in real apps. I think this is because our tsconfig sets a `baseUrl` to allow resolution from the types folder, so the tooling in the RN repo will use that, but it breaks in real apps that don't have that mapping.
This splits all these up into a couple separate directories that are hopefully easier to reason about, and removes `Omit` which has been a builtin type for quite some time (we were actually already using built-in `Omit`).
