[compiler runtime] repro: infinite render with useMemoCache + render phase updates (#30849)

Repro for an infinite render bug we found when testing internally. See
equivalent codesandbox repro
[here](https://codesandbox.io/p/sandbox/epic-euclid-mr7lm3).

When render phase updates cause a re-render, useMemoCache arrays for the
fiber are
[cleared](https://github.com/facebook/react/blob/main/packages/react-reconciler/src/ReactFiberHooks.js#L819)
and [recreated on every
retry](https://github.com/facebook/react/blob/main/packages/react-reconciler/src/ReactFiberHooks.js#L1223)
while hook state is preserved.

This pattern (queuing re-renders on the current fiber during render) is
perfectly valid. I believe this is a bug as React compiler currently
replaces `useMemo`s with `useMemoCache` calls and inlined instructions,
taking care to preserve existing memoization dependencies. This should
be the identity transform, but runtime implementation differences mean
that uncompiled code behaves as expected (no infinite render) while
compiled code fails to render.
