Support TiDB unary minus pushdown #10746

@windtalker

Description

@windtalker

Enhancement

TiFlash should support pushing down TiDB unary minus scalar functions (UnaryMinusInt, UnaryMinusReal, UnaryMinusDecimal).

At the moment, plans containing these TiDB signatures cannot be executed in TiFlash with TiDB-compatible semantics. We should add the DAG mapping, dedicated execution functions, and coverage for unit, query, and fullstack execution.
