artifact_stages: upload LLVM's HEAD SHA with PGO artifacts

It's helpful if we have a small JSON file that describes the LLVM we
built PGO on to go with our uploaded PGO artifacts. This CL adds that
JSON file to our uploaded artifacts.

This file is expected to be <100 bytes, so no compression/etc. is done.

It can be packed in the profile tarball if people want, but it's easier
to work with (e.g. via `gsutil cat`) if it's not.

BUG=None
TEST=./run_tests and a pgo-generate tryjob
