allow building for Intel architecture

Don't see any reason why project can't be built for Intel arch. I understand that D3DM stuff won't work, but not all Windows programs/games need it. Tested the change successfully to run Diablo 2.

When building release, you'd have to pass ARCHS=arm64 to xcodebuild additionally, e.g.:

xcodebuild archive -scheme Whisky ARCHS=arm64

Alternatively, create xcconfig with contents ARCHS = arm64 and pass it to xcodebuild in -xcconfig param. (creating a new build configuration just for that is an overkill)

We don't support Intel primarily because of differences in GPU limitations between the two architectures and our inability to offer support to regular end users. Technical individuals are expected to understand that they can build for Intel if they want to.

This is exactly the goal of the PR - to simplify this process. I'm not asking you to make releases with Intel support which should be clear from xcodebuild examples provided in description.

Alternatively, I can provide xcconfig file that restores Intel support.

Building the GUI isn’t enough you’d also need to provide your own custom build of WhiskyWine that doesn’t bundle Apples D3DMetal since that only works on Apple Silicon.

There was someone who forked and made an Intel build but haven’t updated it since last year.
