[TestUtils] Build limited test-utils (#28782)

We landed a flag to disable test utils in many builds but we need to
fork the entrypoint to make it work with tests properly. This also
removes test-utils implementations from builds that do not support it.
Currently in OSS builds the only thing in test-utils is a reexport of
`act`
