[roll] Roll fuchsia Revert "Reland "[test_manager] Use mocks to collect debug data""

This reverts commit feb45c2f9e5cc1f8d3600cf9fb55870f8c284e8b.

Reason for revert: Still flaking, but not as much fxbug.dev/117876

Original change's description:
> Reland "[test_manager] Use mocks to collect debug data"
>
> The underlying issues with missing debug data in tests has been
> addresssed in fxrev.dev/761894 (CapabilityRequested missing) and
> fxrev.dev/777330 (RealmBuilder local components torn down too early).
>
> Original change's description:
> > [test_manager] Use mocks to collect debug data
> >
> > Switches test_manager over from using the debug_data component to
> > collecting debug data itself, which allows us to remove explicit use of
> > component events to determine the test URL associated with a debug data
> > Publisher connection.
> >
> > This includes a few required, related changes:
> >  * Update to the debug data security policy, as this changes the
> >    location in the topology where the debug data environment is defined
> >  * Update to where testrunner looks to pull debug data off device with
> >    SCP. As this change stops using debug_data, test_manager itself now
> >    hosts the tmp directory containing debug data.
> >
> > After this change, test_manager_for_tests and debug_data are no longer
> > needed and will be cleaned up in a followup.
