De-deprecate parts of the legacy API (#20561)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/20561
We previously planned to deprecate the direct passing of a kernel function or lambda to the op() call, e.g.
static auto registry = RegisterOperators().op("my::op", &func);
and push users towards the options based API:
static auto registry = RegisterOperators().op("my::op", RegisterOperators::options().kernel<decltype(func), &func>());
because that has a slightly lower performance overhead when calling the kernel.
However, that overhead is negligible for all but exotic use cases, so there's no reason to push users towards a more verbose API.
This diff removes the deprecation warning from that API.
However, if you use the API together with deprecated types like std::unordered_map, you will now get a deprecation warning there.
