Replace uses of hash_map in //base
base::hash_map is deprecated in favor of std::unordered_map (which it is a
typedef of).
The changes to tracing required updating of callers in third_party/WebKit.
Some uses were replaced with more appropriate variants: std::map,
base::flat_map, and base::small_map.
A std::hash implementation of base::FilePath is added.
