LUCENE-10081: KoreanTokenizer should check the max backtrace gap on whitespaces
(#272)
This change ensures that we don't skip consecutive whitespaces without checking
the maximum backtrace gap.

> Key: LUCENE-10081
> URL: https://issues.apache.org/jira/browse/LUCENE-10081
> Project: Lucene - Core
> Issue Type: Bug
> Reporter: Jim Ferenczi
> Priority: Minor
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Today the KoreanTokenizer keeps track of the whitespaces that appear before a
> known term in order to apply a space penalty factor. These whitespaces are
> considered part of the next term so the backtrace gap limit is not applied.
> As a result, the position buffer can grow up to the maximum number of
> consecutive whitespaces in the input. This is problematic since the buffer is
> reused on reset() so we should ensure that the max backtrace gap limit is
> applied on consecutive whitespaces consistently.
