rust: Remove support for passing a dict to the Rust pathutil.dirs()
That is only used by the Python dirstatemap, which not used when Rust

This allows removing the private `extract_dirstate` function which
creates `DirstateEntry` values. This in turn will make easier upcoming
changes to `DirstateEntry`.
