canvas: Remove the raqote backend (#38962)

Browse source 
In general, `raqote` is essentially umaintained and has issues with
quality (for instance text rendering has lots of issues) and removing it
finally lets us remove our dependency on `font-kit`. Although,
`vello_cpu` performance is not yet equal to raqote, rendering quality is
a lot better. It's expected that `vello` and `vello_cpu` performance
will keep improving.

Testing: This is covered by existing WPT tests.
