Add hardware_destructive_interference_size

Summary:
[Folly] Add `hardware_destructive_interference_size` and `hardware_constructive_interference_size` to `folly/lang/Align.h`.

As backports from C++17. Which may require keeping, depending on how stanard libraries choose to implement these.

And replace `CacheLocality::kFalseSharingRange` with `hardware_destructive_interference_size`.
