Azure: Rework build the world jobs

Now that we have 3600 minutes per build job, condense and rework things
such that our overall time largely doesn't change, but we can also
largely avoid having to re-tweak this job to avoid timeouts.  Given that
we have 10 threads, we also move a few of the specific sandbox test
builds to a prior stage.

Note that while sandbox builds with address sanitization enabled (ASAN)
not all tests pass, so we limit ourselves to just checking that the
version test passes for now.
