head-revs: add a native implementation of the `stop_rev` parameter
This does not add too much complexity to the native code and help with
branchmap v3 performance.
Note that the final conversion of the heads from native-code to Python is still
too costly, especially in Rust. In addition the current caching around headrevs
is too simple and fragile. However these are an unrelated problem.
