Fix Bug - Handle unsigned long in sorting order assertion of LongHashSet

[Shailesh-Kumar-Singh]

Description

The assertion logic in LongHashSet.java assumes signed long values, which leads to incorrect validation when dealing with unsigned long values. The sorted order check fails because value >= previousValue does not correctly handle unsigned comparisons.
I have described the Bug in detail in the issue - #17206

FIX

1. Added a new constructor parameter (isUnsignedLong) to LongHashSet to indicate whether the values are unsigned.
2. Updated assertion logic:
   • Used Long.compareUnsigned(value, previousValue) >= 0 for unsigned long values.
   • Maintained value >= previousValue for signed values.
3. Refactored assertion check into a new helper method: assertBasedOnDataType().
4. Modified SortedUnsignedLongDocValuesSetQuery.java to pass true when initializing LongHashSet for unsigned values.

Can we add tests similar to TestDocValuesLongHashSet in Lucene ?
