Payload size tracking was temporarily disabled in #31057, due to
`CIRCLE_COMPARE_URL` stopping being available. It turned out this was
related to turning on the new [Pipelines][1] feature, which was required
for testing Windows on CircleCI.
Since then, we have turned `Pipelines` off and got `CIRCLE_COMPARE_URL`
back (e.g. see [build 362971][2]). According to CircleCI, failing to
populate `CIRCLE_COMPARE_URL` with `Pipelines` on is a bug and they are
working on fixing it.

The `CIRCLE_COMPARE_URL` is not available in builds any more since we
enabled `Pipelines` on CircleCI. We have contected CircleCI, but until
this is solved we cannot get the commit range and thus disabling
uploading of payload size data to avoid broken builds.

These files are not needed once the size has been calculated and there
is no point in keeping them around.
Deleting them prevents, for example, uploading unnecessary files from
`aio/dist/` to Firebase (because `deploy-to-firebase.sh` runs the
payload size checks right before deploying).

The scripts were accidentally broken in #20524. More specifically, when a limit
was exceeded the script would break while trying to log an error message due to
a missing `commit` variable.
This commit fixes it and also does some minor clean-up (improve docs, use more
descriptive variable names, remove dead code, etc).
