Allow @nx/js:node executor to run directly against typescript sources without building first

[daiscog]

In a few projects, I've wanted to build a mock server or some other local-only backend using node.

As this will never be released, I don't need a build target - I'd like instead to just run the project directly from its (typescript) source.

It would be great if the @nx/js:node executor could do this for me so I don't have to configure ts-node or swc myself.
