DevTools: fix npm test debugging when using user compiled content shell

Previously, I wasn't copying the metadata files when the user compiled their
own content shell, which is needed for debugging tests.

Also, I've removed the test-only and build-only flags since we no longer
need to copy/build devtools now that we're using --custom-devtools-frontend.
