Add WakeUp and AutoStart Features to MobileNativeCode Plugin

Description

This PR introduces two new features to the MobileNativeCode plugin for Unreal Engine on Android.

WakeUp

• Prevents the Android device from entering Doze Mode
• Keeps Wi-Fi alive even during screen-off or idle state
• Ideal for real-time apps like VR multiplayer or persistent networking
• Restrict:
  • Currently limited to run only while the app is active - this is an intentional design choice
  • To make it work even when the app is closed, simply remove the AppLifecycleObserver restriction, and let the background service run independently

AutoStart

• Automatically launches the application right after device boot
• Implements BroadcastReceiver to detect BOOT_COMPLETED
• Starts a custom background Service to trigger app launch
• Verified functionality on Meta Quest (Android VR device)

Testing

• Tested on Meta Quest 2
• Both features function reliably across multiple reboots and idle/wake cycles
• No noticeable performance or battery issues during usage

Changes

• Added new Java classes: WakeUpHelper.java, AutoStartReceiver.java, BootService.java
• Modified plugin AndroidManifest.xml to declare permissions and services
• Exposed native methods to Unreal via JNI for enabling these features

Notes

• AutoStart requires RECEIVE_BOOT_COMPLETED and proper system permission
• WakeLock is used carefully to avoid battery abuse; it's released appropriately
• No changes were made to existing plugin logic
