feat: Add 10GB, 12GB, 14GB, and 16GB DRAM configuration options

- Extended MemoryLayout enum with new memory size options
- Added corresponding SMC memory size and arrangement constants
- Updated system control functions to handle new memory configurations
- Added appropriate application pool sizes for higher memory modes
- Updated UI translations to display new DRAM options as "Unsafe"
- Increased maximum memory layout setting from 8GB to 16GB

This allows users to configure higher memory amounts for games and
texture mods that require more than the standard 4-8GB configurations.
All new options are marked as "Unsafe" in the UI to indicate they
are experimental features beyond Nintendo's official specifications.
