Relax table name detection in `from` to allow any extension like INDEX hint
#35360 allows table name qualified if `from` has original table name.
But that is still too strict. We have a valid use case that `from` with
INDEX hint (e.g. `from("comments USE INDEX (PRIMARY)")`).
So I've relaxed the table name detection in `from` to allow any
extension like INDEX hint.
Fixes #35359.
