Extract maven-resolver-api from the embedded runtime bundle

Currently we embed the maven-resolver-api jar into m2e, but the API
itself is already a bundle an we should consume it as such so we can:

1) update it independently
2) make it reusable by others without require the full runtime
3) cut down the size of the runtime bundle
