This reverts commit cff2617b.

Reason for revert: Breaks https://ci.chromium.org/p/v8/builders/ci/V8%20Win64%20-%20msvc/13100?

Original change's description:
> cppgc: Stack scanning support for Windows native
> 
> Assumes that (is_clang = false && is_win) => Windows native (MSVC).
> 
> Cross-compile builds will use clang and not the native tools and thus
> not fall into this category.
> 
> This CL adds x86 and x64 MASM trampolines that can be used with the
> native Windows toolchain (ml.exe, ml64.exe), when using is_clang =
> false.
>
