Abort pending requests if the cache entry is removed

[markerikson]

This PR:

• Updates the RTKQ internals to rearrange the API instance setup in module.ts so that buildInitiate() is called before buildMiddleware(), and then makes getRunningQueryThunk available to buildMiddleware
• Updates cacheCollection.ts to:
  • Ignore any subscription entries with a "_running" postfix when checking if there's still an active subscription to that cache entry. Those indicate a pending request, not a full subscription, and can exist even if there are 0 true subscribers (ref: keep subscription on data while query is running #3709 , BUG: UseLazyXXXQuery Returning undefined On Long Running Queries  #3706 )
  • Only run handleUnsubscribe() if there's still an actual cache entry at that time
  • When we do remove the cache entry, first check if there's a running query, and if so call .abort() on it
• We already expose the abort signal into the retryCondition callback, via extraArgs.baseQueryApi.signal. Added a test to verify it gets marked as aborted if we have aborted the in-flight request.

Fixes #4942
