Removes the task snapshot's reference earlier from the persist queue. 

If the previous write request is duplicated from the latest request.

Flag: com.android.window.flags.release_snapshot_aggressively
Bug: 238206323
Test: use swipe-up gesture to close an app, which will has two take
task snapshot request. Verify only one screenshot reference in dmabuf
since previous request can be released as soon as possible.
