EveyWu updated CALCITE-6278:
----------------------------
Description:
Add Spark functions that have been implemented but have different
OperandTypes/Returns.
Add Function
[REGEXP|https://spark.apache.org/docs/latest/api/sql/index.html#regexp]
Since this function has the same implementation as the Big Query
[REGEXP_CONTAINS|https://cloud.google.com/bigquery/docs/reference/standard-sql/string_functions#regexp_contains]
function. the implementation can be directly reused.
