Description

Refactored built-in string functions to enable collation support for: contains, startsWith, endsWith. Spark SQL users should now be able to use COLLATE within arguments for built-in string functions: CONTAINS, STARTSWITH, ENDSWITH in Spark SQL queries. Note: CONTAINS implementation for non-binary collations is a separate subtask (SPARK-47248).
