Reland Memory64 atomic operations
https://bugs.webkit.org/show_bug.cgi?id=314004
rdar://176203709
Unreviewed. Relanding 311812@main
The original patch: https://commits.webkit.org/311812@main was reverted because
it relied on this bulk memory patch: https://commits.webkit.org/311796@main,
which caused
some failures in JetStream.
The bulk memory patch was fixed here: https://commits.webkit.org/312534@main,
so I am
relanding the atomics changes.
