The ChunkIterator now limits a chunk to using only one font (before, it was possible to have a chunk with >1 font, when `unicode-range` CSS property is used). This change allows us to reduce some complexity in the text shaping and painting code and makes us compatible with the APIs in Skia and HarfBuzz.
