### What changes were proposed in this pull request?
This pr upgrade Apache Arrow from 13.0.0 to 14.0.0.

### Why are the changes needed?
The Apache Arrow 14.0.0 release brings a number of enhancements and bug fixes.
‎
In terms of bug fixes, the release addresses several critical issues that were causing failures in integration jobs with Spark([GH-36332](apache/arrow#36332)) and problems with importing empty data arrays([GH-37056](apache/arrow#37056)). It also optimizes the process of appending variable length vectors([GH-37829](apache/arrow#37829)) and includes C++ libraries for MacOS AARCH 64 in Java-Jars([GH-38076](apache/arrow#38076)).
‎
The new features and improvements focus on enhancing the handling and manipulation of data. This includes the introduction of DefaultVectorComparators for large types([GH-25659](apache/arrow#25659)), support for extended expressions in ScannerBuilder([GH-34252](apache/arrow#34252)), and the exposure of the VectorAppender class([GH-37246](apache/arrow#37246)).
‎
The release also brings enhancements to the development and testing process, with the CI environment now using JDK 21([GH-36994](apache/arrow#36994)). In addition, the release introduces vector validation consistent with C++, ensuring consistency across different languages([GH-37702](apache/arrow#37702)).
‎
Furthermore, the usability of VarChar writers and binary writers has been improved with the addition of extra input methods([GH-37705](apache/arrow#37705)), and VarCharWriter now supports writing from `Text` and `String`([GH-37706](apache/arrow#37706)). The release also adds typed getters for StructVector, improving the ease of accessing data([GH-37863](apache/arrow#37863)).
