errors: backport ERR_INVALID_PROTOCOL to v8.x

This error code originally landed in a semver-major commit and is used
by the ESM implementation. This backport includes the error message
and the documentation for the error.

I did attempt to write a test for this, but it did not seem possible
to catch an exception during import, I was also unable to execute
`node --experimental-modules` properly inside of a child_process.

I'll dig more into getting a test together, but we should backport
this fix in the mean time.
