chore(core): Refactor runtime and split out tests (#19491)
This is a quick first refactoring to split the tests out of runtime and
move runtime-related code to a top-level runtime module.

There will be a followup to refactor imports a bit, but this is the
major change that will most likely conflict with other work and I want
to merge it early.
