rust-clippy: fix most warnings in `hg-core`

All of these are simple changes that for the most part are clear improvements
and the rest are at most equivalent.

The remaining warnings have to be fixed either with a bigger refactor like for
the nested "revlog" module, or in the dependency `bytes-cast`, which we own.

This will be done sometime in the future.
