commit-reach: move can_all_from_reach_with_flags
There are several commit walks in the codebase. Group them together into a new commit-reach.c file and corresponding header. After we group these walks into one place, we can reduce duplicate logic by calling equivalent methods. The can_all_from_reach_with_flags method is used in a stateful way by upload-pack.c. The parameters are very flexible, so we will be able to use its commit walking logic for many other callers.
