Remove GB emulator code & add meta.json index ordering

[Inter-Raptor]

Motivation

• Fix a compilation/runtime issue caused by leftover Game Boy emulator integration and simplify the launcher to only start native game.bin images.
• Provide a deterministic, user-controllable ordering for games via an integer index in meta.json so prioritized apps appear first.
• Keep the SD sample data consistent with the requested priorities and remove GB/.gb assets from the bundled SD tree.

Description

• Removed Game Boy launch-specific code and header from RaptorLauncher_V4/launcher_ui.cpp so the launcher no longer depends on gb_launch_config.h or the emulationGB code path and now launches only the native game.bin.
• Replaced GameInfo::rom with an integer GameInfo::index in RaptorLauncher_V4/types.h and updated SD parsing in RaptorLauncher_V4/storage_manager.cpp to read index (falling back to legacy indice) and default to 30 when absent.
• Added deterministic sorting in storageListGames(): sort by ascending index then case-insensitive alphabetical name for ties.
• Updated the SD sample metadata under CarteSD/games/*/meta.json to include index values as requested (1: RaptorSDKTestLab; 2: WiFiTouchConsole; 3: DinoBlaster, DinoLife, JurassicBrickBreaker, ParaRunner; others 30) and regenerated CarteSD/games/index.json accordingly.
• Removed the example Game Boy folder and assets (CarteSD/games/PokemonBleu_GB) and other GB emulator remnants from the SD sample to fully drop .gb/emulator artifacts.

Testing

• Ran a JSON parse check with python against all CarteSD/games/*/meta.json and CarteSD/games/index.json, and parsing completed successfully.
• Searched the codebase with rg for GB/emulation symbols and ROM references (gb_launch_config|emulationGB|PokemonBleu_GB|.gb|gb_emulator|"rom"|rom_path) and confirmed no remaining matches in the launcher and SD sample files.
• Inspected the modified source files (RaptorLauncher_V4/launcher_ui.cpp, RaptorLauncher_V4/storage_manager.cpp, RaptorLauncher_V4/types.h) and SD metadata to verify the index read path, defaulting behavior, and sorting logic were applied as described.
