React: "scheduler" package umbrella

[bvaughn]

Short term

• [x] #13561: Replace the __getInteractionsRef and __getSubscriberRef methods with direct mutable exports (__interactions and __subscriber) and update the ScheduleTracking UMD fork.
• [x] #13561: Remove __getInteractionsRef and __getSubscriberRef from the schedule/tracking UMD dev and prod bundles since it's not part of the public API.
• [x] Fix interaction-tracking reference count bug (#13574)
• [ ] Split subscriptions entry point apart from tracking (e.g. break scheduler/tracking into scheduler/tracking and scheduler/subscriptions)

Long term

• [ ] Move scheduler to is own git repo (maybe even its own org) prior to a 1.0 release.
• [ ] Enable it to be used without a build step by replacing the dev/prod check with a single export.
• [ ] Add an ES module entry point as well as the CJS and UMD entry points
