[AbhishekASLK]

This PR annotate CURRENT_CATALOG() function for Hive, Spark and DBX

Documentation:

• Spark
• Databricks

Hive:

SELECT typeof(CURRENT_CATALOG()), version()
+---------+--------------------------------------------------+--+
|   _c0   |                       _c1                        |
+---------+--------------------------------------------------+--+
| string  | 4.1.0 r75e40b7537c91a70ccaa31c397d21823c7528eeb  |
+---------+--------------------------------------------------+--+

Spark2:

SELECT CURRENT_CATALOG()
Spark Version: 2.4.8
Undefined function: 'CURRENT_CATALOG'. This function is neither a registered temporary function nor a permanent function registered in the database 'default'.; line 1 pos 7

Spark:

SELECT typeof(CURRENT_CATALOG()), version()
+-------------------------+--------------------+
|typeof(current_catalog())|           version()|
+-------------------------+--------------------+
|                   string|3.5.5 7c29c664cdc...|
+-------------------------+--------------------+

DBX:

SELECT typeof(CURRENT_CATALOG()), version()
typeof(current_catalog())	version()
string	4.0.0 0000000000000000000000000000000000000000

@georgesittas Hive, Spark3, DBX support this but not spark2 (support Since: 3.1.0), how we can handle this? we have to support individually or this is fine?
