Add a feature flag to enable expiration of retry lanes (#27694)

An attempt to see if we can bring back expiration of retry lanes to
avoid cases resolving Suspense can be starved by frequent updates.

In the past, this caused increase browser crashes, but a lot of time has
passed since then. Just trying if we can re-enable this.

Old PR that reverted adding the timeout:
