fix(tvix/eval): remove incorrect imports when coercing r/7218
The default behavior of string coercion in C++ Nix is to weakly coerce and import to store if necessary. There is a flag to make it strongly coerce (coerceMore) and a flag that controls whether path values have the corresponding file/directory imported into the store before returning the (store) path as a string (copyToStore). We need to implement our equivalent to the copyToStore (import_paths) flag for the benefit of weak coercions that don't import into the store (dirOf, baseNameOf, readFile, ...) and strong coercions that don't import into the store (toString). This makes coerce_to_string as well as CoercionKind weirder and more versatile, but prevents us from reimplementing parts of the coercion logic constantly as can be seen in the case of baseNameOf. Note that it is not possible to test this properly in //tvix/eval tests due to the lack of an appropriate EvalIO implementation being available. Tests should be added to //tvix/glue down the line.
