gamecenter generate_xcframework error when building modules GameKit and simd

[sourencho]

I'm trying to build the plugin libraries on a Apple M1 running Sanoma 14.0 and Xcode 15.0 but I run into an error at the generate_xcframework step.

Here are the steps I took:

1. scons platform=ios target=editor
2. scons target=editor arch=arm64 simulator=no plugin=gamecenter version=4.1.3
3. ./scripts/generate_xcframework.sh gamecenter debug 4.0

Someone posted this on apple forums claiming that the issue is on apple's end, but I wanted to double check here. https://developer.apple.com/forums/thread/740770?login=true&page=1#770668022

I just saw this on the Godot 4 issue thread but thought I'd respond here as it's more relevant. I have not found a workaround yet as it seems to be an Apple SDK issue because it's to do with the import of GameKit.h.

I also tested this with Godot 3.5 and got the same issue, if I can find a way to rollback the iOS SDK version I might try that and see if it works.

Seems like scripts still include armv7, and Xcode 15 doesn't have support for 32-bit iOS anymore. Godot is also built without 32-bit support, so it should be removed.

Just removed all reference to armv7 in code and it works now! Thank you so much.

@nicoformaggio oh nice! Can you share your diff so I can fix it on my end too?
