seperate video decoding thread for each display (#9968)

* seperate video decoding thread for each display

1. Separate Video Decoding Thread for Each Display
2. Fix Decode Errors When Clearing the Queue
Previously, on-flight frames after clearing the queue could not be decoded successfully. This issue can be resolved by setting a discard_queue flag when sending a refresh message. The flag will be reset upon receiving a keyframe.
