Once bitcode support has been removed from the engine #107884, remove --bitcode flags from the recipes. Unify the ios-release-nobitcode and ios-release artifacts. May need to publish both for awhile until customers are informed ios-release-nobitcode is going away?

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.

• Update recipe to upload a no-bitcode version to both buckets
