Update Android build configuration, add new CPU and memory options, and enhance patch manager handling for CTGP

- Updated the NDK version to 28.0.13004108.
- Changed Java source and target compatibility to version 23.
- Enabled resource shrinking and updated ProGuard files.
- Added a new CPU accuracy option ("Safe") and a new memory layout option ("Software").
- Implemented special handling for CTGP patches, ensuring they are processed even if disabled.
- Added logging for better traceability of patch processing.
- Updated memory layout handling in various places to accommodate the new "Software" mode.
