Custom test runner

[black7375]

Clear and concise description of the problem

Jest ecosystem has jest-runner or create-jest-runner.

It can be extended to test in an environment such as an electron. Also, It would be nice to be able to perform lint or typecheck with the efficient worker of tinypool.

Suggested solution

I'd like to provide an API for setting up a custom runner.

Alternative

It can also refer to Jest's projects config.

Ready to hear it 😄

Right now we run our tests in packages/vitest/src/runtime/run.ts. You can look it up for reference
