Cleanup and small feature: remove unused variables and dead switch blocks, fix a missing return, and fix a stop-recording quick menu entry.
Add support for auxiliary screen streaming in the UI and runtime: add sublabel strings for start/stop aux streaming, register sublabel macros and menu bindings, and update menu display logic to account for aux streaming/recording state. Adjust streaming action handlers to check recording/aux state and avoid conflicting starts (early-return to resume when appropriate). Also add DSU-side logging and a runloop message push when a controller is attached to provide user feedback.

These commits implement a complete DSU (Cemuhook) input driver for receiving controller data over UDP, add libretro multi-screen API support for cores with multiple displays (e.g., Nintendo DS), and enable auxiliary screen streaming/recording. The changes include UI integration for aux streaming controls, DSU controller attachment notifications, video-only FFmpeg recording for aux streams, and configuration options for DSU & AUX Screen settings.
Example how cores can make use of the AUX screen stream feature
