Track Size of All ZIP Files

We don't currently track the size of some of the non-binary ZIP files, such as `-symbols.zip` and `-debug.zip`, which means we can't catch regressions there. That's less than ideal as we have seen cases where something went wrong with these files and we didn't notice.

Should be easy enough to start tracking them as well, but we'll probably want to use a looser threshold percentage since these are larger and are more likely to have larger variations.
