rust-dirstatemap: implement part of the `setparents` logic

The Python code does many round-trip calls to the Rust dirstatemap when copy
information needs to be dropped in `setparents`.

This may result in improved performance on `commit`, `update` and other such
commands, but was mostly done to drop the last use of `set_dirstate_item`.
See inline comments for an asterisk about performance, and see next patch for
why `set_dirstate_item` has to go.
