Decoded image data should not continue to traffic in ImmutableBitmap now that the bitmap wrapper is being retired. Introduce DecodedImageFrame as the paintable decoded-image unit and store a Bitmap plus ColorSpace in it directly. Thread the new frame type through decoded image data, display-list image commands, filters, canvas drawImage, patterns, WebGL texture upload, and CSS/SVG image consumers. ImmutableBitmap remains only at the legacy boundaries that still need it, such as HTML video snapshots and callers that explicitly ask for a bitmap snapshot. This keeps color-space ownership with the decoded frame while making the expensive or legacy ImmutableBitmap path explicit at the few call sites that still need it.
