IGNITE-20294: Sql. Using UDF as a place for system_range function

[lowka]

Provides implementation of a table function that does not store its state inside SQL row.

• ScanNode now uses TableFunction instead of an iterable.
• Every scan creates a new instance of table function, and then uses it to produce more rows. When scan completes that instance is closed.

TableFunction - some table function. TableFunctionInstance - concrete implementation of a table function (Scan operator creates an instance of table function per scan. TableFunctionRegistry (for a lack of a better name) converts RexCalls into TableFunctions
