🚀 More Optimizations and SIMD fixes for MSVC & ARM

In this release more optimizations and fixes added:

📌 msvc, simd: fix simd headers for _M_ARM64EC 📌 arm, neon: fix neon support on GCC ARM 📌 msvc bug: dont align types due to "ARM32 = C2719: formal parameter ..." 📌 more optimizations for mat4 / mat3 inv 📌 sse: make use of int domain as default behavior if possible ( compiler may ignore it ) 📌 avx: implement transpose with AVX 📌 avx: optimize avx mat4 scale and mat4 mul 📌 win: suppress C4996; use snprintf() instead of sprintf()

and many others improvements and bugfixes

🎓 Noise

❤️ Sponsorship: Consider become a sponsor for cglm

Supporting cross platform, multiple OS-es and multiple CPUs requires multiple hardwares to test on it which requires extra financial cost. Also sparing time is another big issue while working at somewhere fulltime... Your company can become a sponsor to help:
