In flash attention, we need to enable non direct acc matmul, and also expansion of reduceOp in reduction dimension. The former is needed in FA since we are applying some scaling to the acc of second MMA before feeding it in. The second case is required in FA because ReduceOp/MaxOp is in the backward slice of second MMA's LHS, which would require it to be expanded in K2/reduction dim as well.
