fix(ivy): don't update parent pointers in the ivy switch transform (#27170) 

Now that the Ivy switch transform uses ts.getMutableClone() to copy
statements, there's no need to set .parent pointers on the resulting
updated nodes. Doing this was causing assertion failures deep in
TypeScript in some cases.
