  [mlir][gpu] Fix bug in kernel outlining

The updated version of kernel outlining did not handle cases correctly
where an operand of a candidate for sinking itself was defined by an operation
that is a sinking candidate. In such cases, it could happen that sunk
operations were inserted in the wrong order, breaking ssa properties.
