d16f42d1 - [mlir][linalg] Constrain the parameters m, r in Winograd ops (#144657)

[mlir][linalg] Constrain the parameters m, r in Winograd ops (#144657) We only support fixed set of minimum filtering algorithm for Winograd Conv2D decomposition. Instead of letting users specify any integer, define a fixed set of enumeration values for the parameters of minimum filtering algorithm.
