Now in `TransportRequestHandler.processStreamRequest`, when a stream request is processed, the stream id is not registered with the current channel in stream manager. It should do that so in case of that the channel gets terminated we can remove associated streams of stream requests too. This also cleans up channel registration in `StreamManager`. Since `StreamManager` doesn't register channel but only `OneForOneStreamManager` does it, this removes `registerChannel` from `StreamManager`. When `OneForOneStreamManager` goes to register stream, it will also register channel for the stream. Existing tests. Closes apache#23521 from viirya/SPARK-26604.

…treamManager ## What changes were proposed in this pull request? This is mostly a clean backport of #23521 to branch-2.4 ## How was this patch tested? I've tested this with a hack in `TransportRequestHandler` to force `ChunkFetchRequest` to get dropped. Then making a number of `ExternalShuffleClient.fetchChunk` requests (which `OpenBlocks` then `ChunkFetchRequest`) and closing out of my test harness. A heap dump later reveals that the `StreamState` references are unreachable. I haven't run this through the unit test suite, but doing that now. Wanted to get this up as I think folks are waiting for it for 2.4.1 Closes #24013 from abellina/SPARK-26604_cherry_pick_2_4.
