CMake improvements: ccache, bundled Qt, MoltenVK, LTO, and Linux deps (#2622)

Browse source 
- Fix YUZU_USE_BUNDLED_QT on Linux (correct path is gcc_64 for Qt 6.8.3).
- Implement USE_CCACHE correctly (additional changes on #2580).
- Categorize and organize CMake options for clarity.
- Add missing Linux dependencies
- Set CMP0069 (LTO) default behavior to NEW to reduce warnings.
- Replace USE_SYSTEM_MOLTENVK with YUZU_APPLE_USE_BUNDLED_MONTENVK and remove duplicate download_moltenvk.
