try fix FFmpeg amf encode hang (#10283)

Browse Source 
* Possible Causes
  * GPU API Call Hangs: This could occur, though it's less likely.
  * Infinite Loop: If `QueryOutput` always fails and `hwsurfaces_in_queue_max` is zero, the loop will continue indefinitely.
* Proposed Solution
  * A query_timeout patch has been added to FFmpeg with a value of 1000ms, which exceeds the time required to encode a single frame. This allows us to remove the loop.
* Test
  * After removing the loop, no frame encoding failures were encountered during testing. A single call to QueryOutput is sufficient, as it typically consumes about 12ms on a 2K screen.
