Introduce Windows ARM64(native) support across ToyPathTracer,
profiler, and server code paths when building with MSVC(_M_ARM64).
Key changes:
- MathSimd.h/Maths.h:
- Fix NEON movemask constants for MSVC/ARM64 by loading from a uint32_t[]
via vld1q_u32() and using vdupq_n_u32() for highbit.
- enkiTS/TaskScheduler.cpp:
- Provide Pause() implementation on _M_ARM64 using __yield().
- profiler/winmain.cpp:
- AVX feature checks to x86/x64 only and skip on ARM64.
- server/TracyPopcnt.hpp:
- Implement TracyCountBits using ARM NEON intrinsics.
- Implement TracyLzcnt using _BitScanReverse64().
