shim Apple's futex primitives
This is necessary to unblock rust-lang/rust#122408. The documentation for these is available [here](https://developer.apple.com/documentation/os/os_sync_wait_on_address?language=objc). Because the futex wait operations (`os_sync_wait_on_address` et al.) return the number of remaining waiters after returning, this required some changes to the common futex infrastructure, which I've changed to take a callback instead of precalculating the return values.
