What problem does this PR solve?

Issue Number: close #55788

Related PR: #55788

Problem Summary:
This PR implements the enhancement requested in issue #55788, adding an optional third parameter limit to the SPLIT_BY_STRING function. The limit parameter controls the maximum number of splits to perform, limiting the size of the returned array.

Solution

Add optional third parameter limit to SPLIT_BY_STRING(<str>, <separator>[, <limit>])
When limit is positive: split from left, at most limit splits, returning at most limit + 1 elements
When limit is non-positive or not specified: split all occurrences (backward compatible)
Update BE function implementation in function_string.cpp and function_string.h
Update FE function definition in SplitByString.java and StringArithmetic.java
Add constant folding support for the new parameter

Examples:

SELECT SPLIT_BY_STRING('one,two,three,', ',');       -- ["one", "two", "three", ""]
SELECT SPLIT_BY_STRING('one,two,three,', ',', -1);   -- ["one", "two", "three", ""]
SELECT SPLIT_BY_STRING('one,two,three,', ',', 2);    -- ["one", "two,three,"]
SELECT SPLIT_BY_STRING('one,two,three,', ',', 3);    -- ["one", "two", "three,"]
SELECT SPLIT_BY_STRING('one,two,three,', ',', 4);    -- ["one", "two", "three", ""]
SELECT SPLIT_BY_STRING('one,two,three,', ',', 5);    -- ["one", "two", "three", ""]

Release note

[Enhancement] Add optional limit parameter to SPLIT_BY_STRING function to control maximum number of splits.
