[Script] Remove deprecated attributes from Constant AST node (#18066)
[ARITH] Remove deprecated attributes from Constant AST node
Remove the deprecated `s` and `n` attributes from the `Constant` AST node
class in the script parser. These attributes were previously used for
string and numeric constants but are no longer needed in the current
AST implementation.
Updated all code that creates `Constant` objects to remove the
corresponding parameters:
- Removed `s` and `n` parameters from `Constant.__init__`
- Updated `_FIELDS` list to exclude deprecated attributes
- Fixed calls in `evaluator.py` and `parser.py` to remove extra arguments
This change simplifies the AST structure and removes unused legacy code.
