Original issue's description:
> Implement a runtime headless mode for Linux
>
> This patch implements a runtime headless mode (i.e., a
> --headless command line switch) that makes it possible to
> use a regular Chrome binary as a headless. When the binary
> is launched with this switch, the main entrypoint calls
> into the Headless Shell entrypoint, effectively starting
> that shell instead of Chrome.
>
> To make this possible we must remove the dependency from
> Headless to Ozone, because Ozone is a build-time feature
> which is generally not enabled for regular Chrome builds.
> In practice this means implementing a new headless-specific
> WindowTreeHost and modifying various graphics and input
> entrypoints to do something appropriate in headless mode.
>
> Since many of the modifications are in platform-specific
> code, this initial patch only adds headless support in Linux.
> Other platforms will be added later.
