[mlir][memref] Remove incorrect `memref.transpose` fold (#79809)

This folded casts into `memref.transpose` without updating the result
type of the transpose op, which resulted in IR that failed to verify for
statically sized memrefs.

i.e.

```mlir
%cast = memref.cast %0 : memref<?x4xf32> to memref<?x?xf32>
%transpose = memref.transpose %cast : memref<?x?xf32> to memref<?x?xf32>
```

would fold to:

```mlir
// Fails verification:
%transpose = memref.transpose %cast : memref<?x4xf32> to memref<?x?xf32>
```
