LUCENE-8719: Traverse all paths at the end of a TokenStream in
FixedShingleFilter
> FixedShingleFilter can miss paths at the end of a TokenStream
> -------------------------------------------------------------

>
> If we have a set of paths of differing lengths at the end of a TokenStream,
> FixedShingleFilter will currently stop when the first path hits the end of
> the stream, but this may miss extra longer paths. For example, the stream "a
> b:3/c d e f" with a shingle size of 3 should produce paths "a b f", "a c d",
> "c d e" and "d e f", but at the moment FixedShingleFilter will stop when it
> finds that the path "b f" is too short to produce a shingle.
