There are now only a handful of buildbot jobs remaining and the concern over
outdated treeherder exclusion profiles has largely been resolved.
This does remove the tc() group from a substantial number of tasks which will
now show up as top level tasks, potentially adding clutter. In some cases, we
might want to re-add a new group (e.g group builds or compiled tests together).
However rather than try to predict the best group names for tasks I'm unfamiliar
with, I think it's best to land this as is. Then if things are looking too
cluttered at the root namespace, file follow-up bugs as needed.

This change fixes symbol upload to use a token stored in the Taskcluster
secrets service instead of the token stored in the private Docker image.
Additionally, it changes the script to upload symbols to the Tecken staging
server when run on try so that the upload-symbols tasks can be tested on
try now. In the future there are plans to allow try tasks to upload symbols
to a separate storage area on the production Tecken instance.
