Video: Add WPT Test for MediaRecorder HEVC Support
Also, change the usage of createVideoFrame() to
`createFlowingVideoStream() to resolve an issue:
For video encoding on macOS, when the second HEVC
compression session is created, and when GPU is x64
arch, MaxKeyFrameIntervalDuration of VT may suddenly
became unsupported, this changes the encoder behaviour,
resulting CompressionCallback() won't always be
triggered immediately when the first frames came,
So we need the video stream to constantly generate new
frames to make sure the test passes.
