[clang] [llvm] Adjust MSVC disabled optimization pragmas to be _MSC_VER only (PR #116704)

[Simon Pilgrim via cfe-commits]

https://github.com/RKSimon created https://github.com/llvm/llvm-project/pull/116704

Alter the #ifdef values from #110986 and #115292 to use _MSC_VER instead of _WIN32 to stop the pragmas being used on gcc/mingw builds

Noticed by @mstorsjo
