[roll] Roll fuchsia Revert "[dso_runner] Initial skeleton"

Original change's description:
> [dso_runner] Initial skeleton
>
> Basic core functionality that supports sync and async components that
> share an address space. This changelist includes:
>
> - "synchronous" components - components that get a dedicated
>   thread
> - "async" components - components that run in a shared Fuchsia Driver
>   Framework thread pool, much like components in driver runner.
> - Component lifecycle support for start/stop/exit
> - Unit tests
> - Simple example (//examples/components/dso)
>
> Not included/upcoming in future changes:
>
> - Namespacing support for either sync or async components. For now they
>   share the same global namespace/fdio/etc. as the runner process.
> - Running the components in a separate address space for the runner.
>   This currently isn't too important since all the DSO components share
>   the same address space, but it could become relevant when/if we
>   support multiple "containers".
> - Integration test - I want to have this but I think it makes sense to
>   land the namespacing support first.
> - Routing of dso_runner in the component topology
