qmuntal b6f29d2365 runtime: implement high resolution timer on windows arm/arm64 
This CL moves the usleep2HighRes from assembly to good old Go.
This is safe because since CL 288793 usleep is always called with
a g, else one wold have to call usleep_no_g. This condition was
not enforced when high resolution timers were first implemented
on Windows (CL 248699), so the implementation was done in assembly.

Other than removing a bunch of obscure assembly code, this CL makes
high resolution timers work on windows arm/arm64 by free, as the
system calls are the same in all windows platforms.
