Reland "Cleanup web engine recipes."

This is a reland of commit 7c10996dac7fb27a5de9911d1df03dfe53efa292

Original change's description:
> Cleanup web engine recipes.
>
> This is paying some technical debt in the web engine recipes and
> improving the usability of the builds UI.
>
> The list of changes included here:
>   * Remove fuchsia_ctl recipe not used anymore.
>   * Migrate web engine recipes to shard_util_v2
>   * Remove adhoc gn/build methods and use api.build_util instead
>   * Remove non required contexts to improve readability of the code.
>
> A few benefits of these changes:
>
>   * A few minutes will be saved on the execution time
>   * Now it is possible to test drone changes with led with no additional
>     steps
>   * UI is now presenting sub-builds with proper names.
