dirstate: Removed unused instances of `DirsMultiset` ? in Rust-backed dirstatemap. The Python class `dirstatemap` had cached properties `_dirs` and `_alldirs` that were not used for `hastrackeddir` and `hasdir` since they were redundant with corresponding fields for the Rust `DirstateMap` struct. `dirfoldmap` is modified to reuse instead the directory iterator introduced in 3b9914b28133c0918186b6e8b9e4f1916e21338d.
