These methods would previously fail on the other `Installable`s, so moving them to this class is more correct as to where they actually work. Additionally, a `InstallableValueCommand` is created to make it easier (or rather no worse than before) to write commands that just work on `InstallableValue`s. Besides being a cleanup to avoid failing default methods, this gets us closer to https://github.com/NixOS/rfcs/pull/134.
