Disable bitcode for OneSignalNotificationServiceExtension

[stopiccot]

Fix for the #540

According to Xcode documentation bitcode is no longer supported by Xcode 14

https://developer.apple.com/documentation/xcode-release-notes/xcode-14-release-notes

Starting with Xcode 14, bitcode is no longer required for watchOS and tvOS applications, and the App Store no longer accepts bitcode submissions from Xcode 14.

Xcode no longer builds bitcode by default and generates a warning message if a project explicitly enables bitcode: “Building with bitcode is deprecated. Please update your project and/or target settings to disable bitcode.” The capability to build with bitcode will be removed in a future Xcode release. IPAs that contain bitcode will have the bitcode stripped before being submitted to the App Store. Debug symbols for past bitcode submissions remain available for download. (86118779)

seem like this is necessary for Xcode 14+ which is enforced from 2023 April, otherwise, we need to manually set it in the post process. also need to care about the order of the post process.
