Second attempt to "Rewrite atomic.h to use stdatomic.h."

This should not be committed until win_sdk and aarch64 builds are
fixed in the presence of this CL.

This reverts commit 2789faabfa9cdf16902a52a1de3fc4a7ae98efed.

We additionally remove uniprocessor support from the earlier CL,
thus avoiding a potential compiler code reordering issue.
