• Switch to x86_64 cross tools for VS
• Fix compile errors on FFmpeg

[bear101]

I still cannot build win32 using the vcvarsamd64_x86.bat. I get a bunch of linker errors in FFmpeg.

[hwangsihu]

Could you please send me the exact error message? The build works fine for me.

Here's build errors I get when linking:

HMM, Did you test this on the latest commit? It compiles normally in GH Actions without these errors.

Yes, latest commit. It fails with the same error both with the "cross tool" and normal "x86" VS command prompt.

I also mentioned the build issue here: #3162

I wonder if it's because I'm using some different version of CLang on Windows.

[hwangsihu]

Doesn't WebRTC only use Clang? Anyway, try using CLANG for MSVC.

[bear101]

What is the purpose of this PR?

[hwangsihu]

When compiling to 32-bit on a 64-bit system, it is recommended to use cross-tools instead of native tools, because the compiler is 64-bit, not 32-bit. It also resolves the build error that @CoBC is experiencing.
