After the initial migration to std::filesystem, we still have a lot of
leftover roundtrip conversions from `fs::path` to `string` and back to
`fs::path`.

Here, we remove some of those roundtrips where straightforward.
Where removal is non-trivial, we still leave `fs::path` to `string`
conversions, but remove the additional round-trip via `char *`.
