Use the display specific DarkIconDispatcher in most places

This will make sure that most icons/components in the status bar
use per display colors.

- Provide a display specific DarkIconDispatcher in
  HomeStatusBarComponent
- Components within this Component now inject the display specific
  instance

Places that use the SysuiDarkIconDispatcher#darkChangesFlow still
have to be updated in a follow up CL.
