LSPosed module: Miracast Enabler v2.0.0

Rewrite from KernelSU shell scripts to LSPosed/Xposed module.
Hooks Android's hidden Wi-Fi Display framework to enable native Miracast.

- FrameworkResourceHook: force config_enableWifiDisplay = true
- SystemServerHook: grant WFD permissions, force wifi_display feature
- DisplayManagerHook: ensure WifiDisplayAdapter initializes, force FEATURE_STATE_ON
- MediaRouterHook: unhide WFD routes in Settings Cast UI
- MiracastTileService: Quick Settings tile for scan/connect/disconnect
- SettingsActivity: resolution, HDCP, display source, GPU composition
- WfdManager: reflection wrapper for hidden DisplayManager WFD APIs
