The C functions are guaranteed to never fail since Windows XP. Also changes the frequency counter to be lazily initialized on demand (when needed) instead of always initializing it during program bootstrap.
Returns the current time as per the monotonic clock in nanoseconds. Doesn't fail (i.e. doesn't raise) and doesn't allocate into the GC HEAP, so we can use it in tight contexts.

The first two commits are straightforward. They mostly do a bit of cleanup. Details are in the commit descriptions.
I'm not sure about the third one: it's meant for #14618 where I want the monotonic time as a basic integer, yet can't have it allocate memory (GC may not be initialized) and raising would be an issue (
.monotonicmay raise on ).
