Repurpose upload script to read natively generated histogram json.

This script will be used when tests write proto-backed JSON. It still
has to reside source-side because we need to access the catapult Python
API to get at HistogramSet and reserved_infos, etc.

WebRTC tests will write proto-backed JSON, and this script can read
it because the Histogram class has been made capable of doing it.
Build information diagnostics are added, and then we upload in the
old JSON format (the dashboard can read the new format as well, but
there's no reason to implement export to the new format at this point).

We could imagine more outlandish solutions where the test binaries
themselves do the uploading, but then we would have to pass the
build information to them, and they would have to upload from the
shards. Alternatively, we could pass build information to tests so
they write it right into the histograms.

This solution is probably the best one for now since it's
1) consistent with how Chromium does it
2) flexible in the right ways
3) we don't have to worry if uploading from shards even works.
