Fix error of non-mappable udtf query in align by device while existing any devices' data cross region

[JackieTien97]

This pull request updates the device view aggregation logic in the query engine to better handle User-Defined Table Functions (UDTFs) and clarifies when special processing is needed. The main changes involve extending the special-case handling to include UDTFs and refactoring related method names for clarity.

Device view aggregation logic improvements:

• Updated the comment in Analysis.java to clarify that deviceViewSpecialProcess applies when all Aggregation Functions, UDTFs, and DIFF are present, not just Aggregation Functions and DIFF.
• Modified the logic in SourceRewriter.java so that special processing for device views is triggered when UDTFs are present, in addition to existing conditions. This is achieved by checking for the UDTF function type in the relevant method.
• Added FunctionType import in SourceRewriter.java to support the new UDTF check.

Code clarity and maintainability:

• Renamed the method aggregationCannotUseMergeSort() to cannotUseAggMergeSort() in SourceRewriter.java for improved readability and accuracy. [1] [2]
• Updated all method calls and logic to use the new method name and signature.
