[ES|QL] Improve arithmetic unary expression nodes #189258

Open vadimkibana opened 3 months ago

vadimkibana commented 3 months ago

For unary arithmetic expressions, say -column, the constructed AST is modified to create a binary expression where column is multiplied by -1. So, -column is transformed to -1 * column. Instead we should just create a unary expression function call node. We are already doing that for NOT unary expressions, like NOT column.
