Move bundle, git, and hub resolver pkgs over

Part of #4710

`pkg/resolution/resolver/bundle/bundle.go` is rewritten here based on `pkg/remote/oci/resolver.go`. This is cleaner code than the original, and retains the original Pipeline bundle resolution behavior of falling back to reading layers as raw if there were errors in reading them as tarballs, rather than only reading layers as raw if there's no matching digest.
