hg-core: remove the `Operation` trait There is no way to currently define a trait which can both return references to `self` and to passed data, which is what we would need. Generic Associated Types may fix this and allow us to have a unified interface. See: rust #44265 Differential Revision: https://phab.mercurial-scm.org/D8862
