prefs: Move some DebugOptions to Preferences and clean up (#34998)

Browse source 
- Move options configuring antialiasing and WebRender shader precache to
  the `Preferences` to group them with other related WebRender and DOM
  settings.
- Remove the option to disable antialiasing for canvases. This was
  unused.
