Bug fixes & minor changes

• [ALL]: Security fix to address a heap overflow issue that could occur when using a model containing an invalid precompiled normalization model.
• [Python]: Deprecates the wheel package for Linux i686.
• [Python]: Supported wheel for Windows Arm64. #1114
• [Python]: Fixed the crash issue on batch decoding #1051
• [ALL]: Updated the Unicode normalization rule with the latest ICU/Unicode rules.
