Use QueryPerformanceCounter as fallback timer on non-x86 mingw

Browse source 
The QueryPerformanceCounter implementation previously was within
defined(_MSC_VER), but it works just as well on other Windows
toolchains, like mingw.

For most common mingw x86 build configurations, one of the earlier
inline assembly implementations would end up used, but for non-x86
(arm, aarch64), it would end up falling back on the gettimeofday
implementation.

This implementation did build successfully (as mingw toolchains do
provide gettimeofday, contrary to MSVC), but the header providing
gettimeofday, <sys/time.h>, wasn't ever included when building
targeting Windows - thus the function was called without a proper
declaration.

Clang 15 changes such implicit function declarations into a hard
error by default, when building in C99 mode (or newer) [1].
(While Clang 15 still is under development, this may still change
before it's released, but it's a valid issue in any case.)
