[sql/tsql] GROUP BY ROLLUP (expression) / WITH CUBE not supported

[lf-novelt]

neither postgres / modern syntax

SELECT DIM_ISO3, c.NAMEWORKEN, INDICATOR, YEAR, Sum(VALUE) AS Total 
FROM pipeline_examples.RLS_DATA r WITH (NOLOCK)
INNER JOIN [pipeline_examples].[REF_COUNTRIES] c  WITH (NOLOCK)
ON c.CODE = r.DIM_ISO3
GROUP BY ROLLUP(DIM_ISO3, c.NAMEWORKEN, INDICATOR, YEAR)

or legacy WITH ROLLUP syntax

SELECT DIM_ISO3, c.NAMEWORKEN, INDICATOR, YEAR, Sum(VALUE) AS Total 
FROM pipeline_examples.RLS_DATA r WITH (NOLOCK)
INNER JOIN [pipeline_examples].[REF_COUNTRIES] c  WITH (NOLOCK)
ON c.CODE = r.DIM_ISO3
GROUP BY DIM_ISO3, c.NAMEWORKEN, INDICATOR, YEAR WITH ROLLUP

are supported.

Same for ROLLUP, CUBE specification of SQL Server.
as we can see the lines are commented out in the PARSER

grammars-v4/sql/tsql/TSqlParser.g4

Lines 4081 to 4086 in ec9ccb7

	group_by_item
	: expression
	/*| rollup_spec
	| cube_spec
	| grouping_sets_spec
	| grand_total*/

Will push the fix in the same branch than my current PR #4651
