C: asm: emulate blendvps using SSE2 instructions
Blend according to (mask & b) | ((~mask) & a).
* c/blake3_sse2_x86-64_unix.S: emulate blendvps using SSE2 instructions for x86_64 unix
* c/blake3_sse2_x86-64_windows_gnu.S: Likewise for x86_64 Windows GNU.
* c/blake3_sse2_x86-64_windows_msvc.asm: Likewise for x86_64 Windows MSVC.
