refactor(compiler-cli): remove usage of `ts.updateIdentifier` (#38076)

With Typescript 4, `ts.updateIdentifier` is no longer available.
Calling `ts.updateIdentifier` used to return the same node when
`typeArguments` was `undefined` because `node.typeArguments`
was also `undefined`.

Relevant TS code:
```js
function updateIdentifier(node, typeArguments) {
  return node.typeArguments !== typeArguments
      ? updateNode(createIdentifier(ts.idText(node), typeArguments), node)
      : node;
}
```
