tests: migrate the pytype test to a shell script for easier CI processing There have been recent hangs and timeout, but it's hard to debug because the *.t test redirects output to a file and only prints it if `pytype` actually exits. This shell script can be run directly by CI, and will allow more flexibility to try to cache and restore type stubs for further speed increases.
