LUCENE-10382: Use `IndexReaderContext#id` to check reader identity. (#702)
`KnnVectorQuery` currently uses the index reader's hashcode to make sure that
the query it builds runs on the right reader. We had added
`IndexContextReader#id` a while back for a similar purpose with `TermStates`,
let's reuse it?
