fix(tvix): ensure PartialOrd/Ord agree for StorePath & NixString

Browse source 
This fixes a *future* clippy lint:
https://rust-lang.github.io/rust-clippy/master/index.html#/incorrect_partial_ord_impl_on_ord_type

In essence, because the implementation of *both* Ord and PartialOrd
implies that ordering is not partial, all results of PartialOrd should
simply be those of Ord. This is to avoid subtle bugs in future
refactorings.
