Started splitting out the timer stuff into its own mini-library. Also I decided to drop the fallback stuff, since we run on new enough systems anyway, and nanosleep() is available on every version of macOS we need anyway.

#include <stdint.h>
typedef int64_t timerDuration;
typedef int64_t timerTime;
Implemented the new MulDiv128 stuff on macOS. To make things easier in regards to signedness, this implementation also uses a base, like the Unix one, and the mach_timebase_info() conversion is done in timerMonotonicTime() instead. (Also added the admittedly-redundant-since-the-current(ish)-implementation-cannot-fail error check to mach_timebase_info().) As a result, timerTimeSub() can now be end - start on all platforms. Also found and fixed bugs in the actual muldiv128 algorithm implementation. Next up: Windows.

#define timerTimeMax ((timerTime) INT64_MAX)
Switched the macOS code to use timerprivInt128ToUint64(). Also rearranged the arguments of timerprivInt128ToInt64() and added proper timerDurationMin/Max constants instead of the incorrect-for-that-function timerTimeMin/Max in the Windows code.
