Remove React Native old architecture (Paper/Bridge) code from iOS, keeping only new architecture (Fabric/TurboModules) code. Changes: - Delete all *ViewManager.m and *ViewManager.swift files (old arch view managers) - Remove #ifdef RCT_NEW_ARCH_ENABLED guards from ComponentView files - Simplify Module.h files to only conform to TurboModule protocols - Remove old arch conditionals from Module.mm files - Update RNMBXViewResolver to remove old arch code paths - Remove unused RCTViewManager imports from Bridge/RNMBX.h and Swift.pre.h - Remove guards from RNMBXFabricPropConvert.mm and RNMBXFollyConvert.h This is a follow-up to the Android old architecture removal (#4128) and continues the 10.3.0 cleanup work (#4118).
