Rhys Hiltner 3f4be127bc Revert "runtime: use semaphore structure for futex locks"
This reverts commit dfb7073bb8 (CL 585636).

Reason for revert: This is part of a patch series that changed the
handling of contended lock2/unlock2 calls, reducing the maximum
throughput of contended runtime.mutex values, and causing a performance
regression on applications where that is (or became) the bottleneck.

Updates #66999
Updates #67585
