The only SkAtomic<T> left are the ones overriding the default memory
order in SkPath. I think I'd like to try switching them to std::atomic
too, but in another CL.
Trim unused APIs in SkAtomics.h.

AtomicTest was the only use of sk_atomic_add().
AtomicInc64 bench was the only use of sk_atomic_inc(int64_t*).

This enables removing the more complicated atomic shims from SkAtomics.h.

This doesn't actually change any API.

We were doing it on Windows, now do it everywhere.
This just changes the backend. We could think about another step to actually
replacing all our sk_atomic_... with std atomic stuff.

We landed this originally with lazily-correct sequentially-consistent memory
order. It turns out that's regressed performance, we think particularly when
recording paths. We also think there's no need for anything but relaxed memory
order here.
We should see this chart go down if all goes well: https://perf.skia.org/#4329
There are also Chrome performance charts to watch in the linked bug.

No public API changes.
