remove use of mach_absolute_time (#15554)

`mach_absolute_time` is one of Apple's required reason APIs (https://developer.apple.com/documentation/kernel/1462446-mach_absolute_time?language=objc). Replace it with the suggested `clock_gettime_nsec_np(CLOCK_UPTIME_RAW)` so that we don't need a RRA entry in a privacy manifest.
