copies-rust: use imrs::OrdSet instead of imrs::HashSet

This yield small speedup all over the board, and a large one for our slower
cases:

Below are three different benchmark comparing this changeset to:
* the previous one,
* the implementation based on `is_anscestors`,
* the filelog copy tracing.
