[mlir][memref] Update tests to use memref.assume_alignment properly. (#142358)

With
llvm/llvm-project@ffb9bbf,
memref.assume_alignment op returns a result value. The revision updates
the tests to reflect the change:

- Update all the lit tests to use the result of memref.assume_alignment,
if it is present.
- Capture the result of the op in lit tests.
