Expression simplifier treats arithmetic negation as bitwise NOT

[Amogh-2404]

Describe the bug

Expr::Negative represents unary minus, but the expression simplifier applies bitwise-NOT identities to it. This produces wrong results for expressions combining unary minus with bitwise AND, OR, or XOR.

To Reproduce

SELECT i, (-i) & i, i | (-i), (-i) ^ i
FROM (VALUES (5), (6)) AS t(i);

Current result:

5  0  -1  -1
6  0  -1  -1

Expected result:

5  1  -1  -2
6  2  -2  -4

Double negation can also hide overflow:

SELECT -(-CAST(-128 AS TINYINT));

This returns -128 after simplification instead of reporting overflow.

Expected behavior

The optimiser should only apply rewrites that are valid for arithmetic negation.

Additional context

Both cases behave correctly when datafusion.optimizer.max_passes is set to 0.
