Version Information
Version of Akka.NET? dev branch
Which Akka.NET Modules? Akka.Streams

Describe the bug
There is tentative evidence that ISourceRefs are not completed and/or being pinned in memory and causes memory leaks.

Reproduction
Will need to create multiple substream that uses ISourceRef and see if they're pinned or not.

@Arkatufus I am willing to bet that these two are the same issue #7125

Fix StreamRef termination detection (akkadotnet#7647)
2b1b5fc 
Solves issue with slow StreamRef termination detection when remote actors terminate abruptly. Added immediate termination detection to SinkRefImpl when data is actively flowing, similar to existing SourceRefImpl behavior. Added tests to verify the fix.

Fixes akkadotnet#7647, related to akkadotnet#7611 and akkadotnet#7125.
