Aliaksandr Kalenik 698bca686e LibGfx+LibWeb: Cache SkImage in ImmutableBitmap ...

By caching the SkImage that is reused across repaints, we allow Skia t
optimize GPU texture caching.

ImmutableBitmap is chosen to own the SkImage because it guarantees that
the underlying pixels cannot be modified. This is not the case for
Gfx::Bitmap, where invalidating the SkImage would be challenging since
it exposes pointers to underlying data through methods like scanline().
