Create libs/test-utils-vitest (#5703)

* Create libs/test-utils-vitest

Copies all files from libs/test-utils that rely on `jest` and migrate them to use `vitest` instead. This will enable any packages that currently use libs/test-utils to be migrated to vitest by using the vitest version of these utils. Eventually, when we're done migrating and there are no more jest tests, we can move these back into libs/test-utils, replacing the jest versions.

* Regenerate CircleCI config
