DecodedImageFrame now owns decoded bitmap pixels directly, so the separate ImmutableBitmap wrapper no longer carries useful semantics. Remove the class and pass decoded image frames or bitmaps at the boundaries where pixels are actually required. The Skia image cache now keys off DecodedImageFrame, matching the display-list commands that paint decoded images. Video frames stay owned by LibMedia, with the explicit YUV-to-bitmap conversion living at HTMLVideoElement's decoded-frame entry point for canvas and WebGL callers.
