Since @rnmapbox/maps 10.3.0 only supports React Native's new architecture, this removes all old architecture related code from Android: - Delete android/src/main/old-arch directory with generated specs - Remove isNewArchitectureEnabled() checks from build.gradle - Remove IS_NEW_ARCHITECTURE_ENABLED BuildConfig field - Always apply com.facebook.react plugin (required for new arch) - Simplify ViewTagResolver to always use FABRIC UIManager - Remove old arch event emission fallback in RNMBXLocationModule - Update RNMBXPackage to always use isTurboModule=true for TurboModules - Delete unused EventEmitter.java (was only used for old arch events) - Delete scripts/codegen-old-arch.js and remove from autogenerate.mjs - Update CONTRIBUTING.md to remove old-arch references The new architecture codegen by React Native's Gradle plugin now generates the required specs during build.

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).
