feat(video_core): implement comprehensive VRAM management system 3e2137a470

Add automatic VRAM leak prevention with configurable garbage collection
to prevent device loss crashes during extended play sessions.

New Settings:
- vram_limit_mb: Configurable VRAM limit (0 = auto-detect 80%)
- gc_aggressiveness: Off/Light/Moderate/Heavy/Extreme levels
- texture_eviction_frames: Frames before texture eviction (default 2)
- buffer_eviction_frames: Frames before buffer eviction (default 5)
- sparse_texture_priority_eviction: Prioritize large sparse textures
- log_vram_usage: Enable VRAM statistics logging

Core Changes:
- Enhanced texture cache with LRU eviction and sparse texture priority
- Enhanced buffer cache with configurable eviction thresholds
- Added VRAM pressure monitoring using VK_EXT_memory_budget
- Emergency GC triggers at 90%/95% VRAM usage thresholds

Platform Support:
- Desktop: Settings in Graphics > Advanced tab
- Android: Settings in Zep Zone category

Fixes VRAM climbing steadily during gameplay until device loss.
Target: Stable VRAM usage below configured limit for 2+ hours.

refactor(settings): simplify VRAM usage mode to Conservative/Aggressive 8eaa38540c

The removed modes added complexity without significant benefit now that
the new VRAM management system (gc_aggressiveness, vram_limit_mb)
provides finer-grained control over memory pressure.
