[Size reports] Script improvements (2/3) (#12947)

#### Problem

Recent memory size investigations suggest some improvements:

- Scripts use PR==0 to distinguish pull requests from master commits
  (push events), but it would be useful to record the associated PR
  along with commits.
- Sometimes push events run on pull requests, and those are not
  currently distinguishable from master push events.
- Sorting by build timestamp is inaccurate, since CI runs may finish
  in a different order than the commits.

#### Change overview

This is the second of three steps. The first step added `event`
and `ref` handling.

This step adds the `event` to artifact names, so that reporting can
stop assuming PR==0 indicates a push event.

The third and final step will add the PR number for pushes to master,
extracted from the commit message.

#### Testing

Only exercisable in CI.
