Previously, the useEvent implementation made use of effect infra under the hood. This was a lot of extra overhead for functionality we didn't use (events have no deps, and no clean up functions). This PR refactors the implementation to instead use a queue to ensure that the callback is stable across renders.

Additionally, the function signature was updated to infer the callback's argument types and return value. While this doesn't affect anything internal it more accurately describes what's being passed.

useMemoCache defines an optional property on the queue hence the compile time check for the flag. But it's not easy to add another compile time check for enableUseEventHook in a way that lets the various permutations of the flags coexist. So I'm opting to just initialize the property on this object in every case for hidden classes and with the assumption that we'll eventually release useEvent (after deciding what to do with naming etc)

Are we doing the "always create a new function in DEV" change? If yes, should we do this here or a separate PR?
