Fix bitcode issues with Toolkit and Samples app

[mhdostal]

There is an issue building the iOS Samples app with the Toolkit using Xcode 14.

Starting with Xcode 14, apple is deprecating the support support for bitcode and we have some build errors related to toolkit with bitcode enabled.

ld: '/Users/sara8187/Library/Developer/Xcode/DerivedData/arcgis-ios-sdk-samples-gfsomrmslqsjpnbnfyxlhzaxfjom/Build/Products/Debug-iphoneos/ArcGISToolkit.o' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. file '/Users/sara8187/Library/Developer/Xcode/DerivedData/arcgis-ios-sdk-samples-gfsomrmslqsjpnbnfyxlhzaxfjom/Build/Products/Debug-iphoneos/ArcGISToolkit.o' for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

According to the release notes:

Unless our plan is to wait until Xcode 14 is released and have that be a minimum requirement, we'll need to continue to include bitcode, which means we'll need to fix whatever is causing the error.

I've responded in what I believe is the originating issue here.

I also think this issue is more tied to the iOS toolkit. I can clone this issue in that repo if you like but I'm not sure this is a toolkit level issue to begin with (as explained in my response linked above).

iOS Samples app addressed it in Esri/arcgis-runtime-samples-ios#1197
Swift Samples app left it as default in the first place, no need to change.
