test: share sdk wrapper xcodegen

[armcknight]

After linking the shared library to the sample apps in #5181, use the shared SentrySDKWrapper.shared.startSentry() call from all swift apps. leaves iOS-ObjectiveC as-is for now as it's the only one using ObjC to initialize the SDK and we need to ensure all those APIs work in ObjC.

Note: there were some differences between the way the SDK wrapper initializes the SDK by default without overrides, and the way the Camera sample would do it. That is addressed in #5201 and #5202
