[platform-expression] add arm32 platform identifier

[strega-nil]

I've noticed people writing arm & !arm64, which just seems really unfortunate. Add an arm32 platform identifier to mean exactly this.

win32 would also be really cool

Unfortunately that one is overloaded and I think would be confusing. For example _WIN32 is a predefined macro on Windows amd64.

Yeah that's right, I mean win32 as windows & !uwp & !mingw

@autoantwort that would be interesting, but I don't know of a good non-confusing name for it.

[autoantwort]

Yeah win32 was the first name I can think of, because uwp is not win32. But I see that the name can be confusing, but I don't know a better one

uwp is not win32

uwp is win32. It sets _WIN32 when compiling.

Hm ok, I am not developing on windows that much, but I thought that (parts) of the win32 API are not available on uwp so that you have to change your application when it should run on uwp.

Maybe desktop-windows-with-msvc ;)
