Replace lipo command with xcodebuild

[data-sync-user]

Right now, we essentially custom build our XCFramework zip file using the lipo command. While this is not an issue per say, The “standard” command to build XCFramreworks is xcodebuild as done by glean https://github.com/mozilla/glean/blob/0104274b9f9080b8e6af132bbe2d0a5d645fd38f/bin/build-xcframework.sh#L21

Note: This is more of a research task in if we can prevent as much manual builds as possible – we might need to keep lipo around for combining uniffi builds before we XCFramework but worth to poke around and investigate.
