Bug 19049 – object.hashOf - don't wrap a public function with an identical public function

This is hashOf in object.d: ``` size_t hashOf(T)(auto ref T arg, size_t seed = 0) { import core.internal.hash; return core.internal.hash.hashOf(arg, seed); } ``` This serves no purpose because `core.internal.hash.hashOf` is public and also has an `auto ref` argument. So `core.internal.hash.hashOf` should either be publicly imported or exposed through an alias. This issue has synergy with PR https://github.com/dlang/druntime/pull/2238.
