Improve performance of ZQuery#run

[kyri-petrou]

The current performance of ZQuery#run if fairly bad, since it does quite a few things:

1. Creates a Scope and closes it
2. Modifies 2 FiberRefs and reverts them

While the cost of run is amortised on large queries, it can become very noticeable when running simple queries.
This PR improves its performance by ~500-600x by:

1. using lower level ZIO methods to handle interruption and addition/deletion of FiberRefs
2. implementing a very lightweight alternative to Scope without all the bells and whistles. This is more than adequate for the usage in zio-query as its only usage is to store potential failures during ZQuery.acquireRelease
