Revert "[darwin] switch blocking mutex from osspinlock to os_unfair_lock"
> OSSpinLock is deprecated, so we are switching to `os_unfair_lock`. However, `os_unfair_lock` isn't available on older OSs, so we keep `OSSpinLock` as fallback.
>
> Also change runtime assumption check to static since they only ever check constant values.
