With the SkImage cache extracted, ImmutableBitmap no longer needs to hold a SkiaBackendContext, an SkImage, or an SkBitmap. Reduce it to just the source pixels (a Bitmap or YUVData) and a color space, so the sam ImmutableBitmap can be consumed by any Skia context without coordination. Per-context locking and ensure_sk_image() are no longer needed and go away with this change; the cache rebuilds an SkImage from the source data the first time each bitmap is drawn against a context.
