[libc++] Merge atomic-wait contention tables into a single table (#208493)

PR #161086 (73a13839d3ec) introduced a new contention table for atomics
with a native size. However, this also increases the size of the dylib
and the footprint of processes using the dylib by a non-negligible
margin.

To mitigate this issue, this change folds the two tables into a single
one. The native waiter count can be stored for free inside padding that
was previously unused.
