feat(video_core): add native ASTC texture cache optimization for Adreno 740+

- Add AndroidAstcMode enum to settings_enums.h (Auto/Native/Decompress)
- Add android_astc_mode setting to settings.h
- Add Adreno 7xx+ GPU detection in vulkan_device (IsAdrenoGpu, IsAdreno7xxOrNewer, SupportsNativeAstc)
- Add compressed_size_bytes field to ImageBase for accurate ASTC VRAM tracking
- Add use_compressed_eviction flag to texture cache for Android-optimized eviction
- Increase VRAM budget to 90% for Android devices with native ASTC support
- Add SupportsNativeAstc() to Vulkan and OpenGL texture cache runtimes

This improves performance on high-end Android devices by allowing more ASTC
textures to be cached when using compressed size for eviction calculations.
