range_search expects the caller to pass the same root twice and starts searching a node for both bounds of a range. It's not very clear that in the early iterations, it searches twice in the same node. This PR splits that search up in an initial find_leaf_edges_spanning_range that postpones aliasing until the last second, and a second phase for continuing the search for the range in the each subtree independently (find_lower_bound_edge & find_upper_bound_edge), which greatly helps for use in #81075. It also moves those functions over to the search module.

Just noticed that my fancy description applies to code in a parallel universe, and this one isn't quite as elegant.

BTreeMap: convert search functions to methods
And further tweak the signature of `search_linear`, in preparation of a better rust-lang#81094.
