Subject: [PATCH] sunfish: Enable full ART optimizations with VDEX/ODEX

Enable comprehensive ART optimizations including VDEX and ODEX
generation for all system components to improve first-boot performance
and reduce application startup latency.

Configuration:
- WITH_DEXPREOPT := true          # Global dexpreopt enable
- DEX_PREOPT_DEFAULT := generate-vdex-and-image  # VDEX+ODEX gen
- WITH_DEXPREOPT_DEBUG_INFO := false  # Exclude debug symbols

Results:
- Verified generation of .odex files (optimized dex)
- Verified generation of .vdex files (verification dex)
- ART images created for core system components
- First boot time significantly reduced
- Application startup latency improved

Test procedure:
1. Full system build with 'm evolution' command
2. Verified artifacts in:
   - system/framework/oat/arm64/*.odex
   - system/framework/oat/arm64/*.vdex
   - system/app/*/oat/arm64/*.odex
   - system/priv-app/*/oat/arm64/*.vdex
3. Confirmed valid ART runtime loading during boot
