Vector algorithms: Add compile time checks for ISA features

[matbech]

When the STL is compiled with /arch:SSE4.2 or /arch:AVX2, the runtime checks for the respective ISA features (SSE42, AVX2) are unnecessary. This change adds a compile time check using __check_arch_support to avoid the runtime cost.

But what is the purpose?

For end users, the STL comes precompiled, so /arch flag passed by users, only affects public headers, but not separately compiled code. And when it is compiled for shipping it is always the same /arch option, which is SSE2 for x86, and baseline for x64.

For custom built binaries (msvcp140_oss.dll) with modern /arch compiler flags where performance is important.
