   Creates new ZManaged from a ZIO value that uses a ReleaseMap and returns a resource and a finalizer.

   The correct usage of this constructor consists of: - Properly registering a finalizer in the ReleaseMap as part of the ZIO value; - Managing interruption safety - take care to use ZIO.uninterruptible or ZIO.uninterruptibleMask to verify that the finalizer is registered in the ReleaseMap after acquiring the value; - Returning the finalizer returned from ReleaseMap#add. This is important to prevent double-finalization.
