1948aa12 - [flang] Do not use dialect conversion in `AffineDialectPromotion` (#156171)

[flang] Do not use dialect conversion in `AffineDialectPromotion` (#156171) This pass uses the rewriter API incorrectly: it calls `replaceAllUsesWith`. This will start failing with #155244. Instead of a dialect conversion, use the walk-patterns driver, which is also more efficient.
