RFR: 8328603: HLS video stream fails to render consistently

[Alexander Matveev]

- When video fails to render AVFoundation outputs frame in `kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange` format which is not supported. We do force format change after that to `kCVPixelFormatType_422YpCbCr8`, but AVFoundation does not provides any video frames after format change. Not sure why it happens.
- When video worked for stream in this issue, then AVFoundation was using `kCVPixelFormatType_422YpCbCr8` for some reason instead of `kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange`.
- I tested format fallback from `kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange` to `kCVPixelFormatType_422YpCbCr8` manually and many streams I tried works fine, except one reported in this bug.
- If AVFoundation is initialized with list of formats JavaFX Media rendering supports, then this issue is no longer reproducible.
- Fixed by providing list of supported formats to AVFoundation.
- Removed unused variable `response`.
- Tested with all streams I have and no issues found.
