refactor(compiler-cli): ensure isNamed....() helpers check name is identity (#38959) (#39272)

Browse Source 
Previously the `node.name` property was only checked to ensure it was
defined. But that meant that it was a `ts.BindingName`, which also includes
`ts.BindingPattern`, which we do not support. But these helper methods were
forcefully casting the value to `ts.Identifier.

Now we also check that the `node.name` is actually an `ts.Identifier`.
