Aliaksandr Kalenik b01060c7d8 Everywhere: Limit layout text fragments to use one font for all glyphs ...

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.

(cherry picked from commit 7181c3f2ea5fba73e77d98acbf9e46640b4a9015,
minorly amended to fix conflicts caused by:
* Our VectorFont not being renamed to Typeface
* Us cherry-picking https://github.com/LadybirdBrowser/ladybird/pull/502
  first
* Us still having bitmap fonts, and hence needing glyph_spacing()

Also amended for:
* AffineDisplayListPlayerCPU changes
* Removing pure virtuals for glyph_id_for_code_point and
  glyph_id_for_code_point in Font.h again since we still have BitmapFont
  which can't implement them
* Updating more Painter methods that we still had
  (Painter::draw_glyph_or_emoji(), Painter::draw_text_run())
)
