Use jest projects instead of custom jest wrapper

This uses Jest's first party support for "projects" instead of passing different config flags to jest. This should make it easier to locally run all variations of a single test and removes all the custom argument parsing.

TODO

  • is the outcome actually easier?
  • look into devtools tests
  • ReactClassEquivalence-test is disabled for now
  • figure out how to handle the "build" variants, I'm thinking those might be a different package.json script that sets an env variable as it's probably rarely used locally (super slow to build before)
