[MSVCRT][CRT][UCRT] Disable intrinsic string functions on MSVC (#9157)

Browse Source 
VS2022 version 17.2 and later (`_MSC_VER >= 1932`) added new intrinsic
functions (`strncmp`, `strncpy`, `wcsncmp`, and `wcsncpy`).
As we implement these ourselves, we have to avoid compiler error C2169.

This problem surfaced with a recent GitHub Actions update:
https://github.com/actions/runner-images/issues/14017

Use `#pragma function(...)` to disable new intrinsic functions.
