Support version upload for Python Workers

[penalosa]

Previously, Python Workers couldn't be used with version upload because there was a difference in module type detection between deploy and version upload. This PR fixes that bug and unifies the two code paths.

After banging my head against the wall trying to figure out how to nicely test this, this PR also introduces a test helper for making assertions against the content of HTTP requests that Wrangler makes. This will work in tandem with MSW (which provides the mock APIs). The issue with our current setup (MSW interceptors making assertions on the content of requests) is that 1) MSW strongly recommends against this style, and 2) probably because MSW recommends against it, it works pretty badly (in particular, stack traces and mismatches in assertions show up strangely)
