  [SDAG][tests] add some test cases covering an add-based rotate (#132842)

Add tests to various targets covering rotate idioms where an 'ADD' node
is used to combine the halves instead of an 'OR'. Some of these cases
will be better optimized following #125612, while others are already
well optimized or do not have a valid fold to a rotate or funnel-shift.
