LUCENE-10264: Clone index input when creating a PointTree in
SimpleTextBKDReader (#478)
Fixes a race condition introduced in LUCENE-9820.

> I noticed a couple of errors in CI regarding the SimpleTextBKDReader which
> are introduced by LUCENE-9820. I had a look and indeed the problem is that we
> are not cloning the index input when creating a PointTree and therefore if
> there are two threads accessing the same PointValue instance (e.g a search
> request and a background merge), then we have troubles.
