Gracefully downgrade FuzzyTermEnum edits from 2 to 1 when term encounters too many states [LUCENE-9104]

When encountering a situation similar to #10140 where a query with max edit distance of 2 causes too many states for the automaton, we could provide the user with an option to accept a reduced set of results instead of an exception since the terms for edit distance of 1 have already been computed anyway.

Migrated from [LUCENE-9104](https://issues.apache.org/jira/browse/LUCENE-9104) by Mike Drob (@madrob)

Start with the FuzzyTermEnum entry point and compare the situation described here with issue #10140. Determine how an option could accept the already computed edit-distance-1 results instead of raising an exception when edit distance 2 exceeds the automaton state limit, and define how completion should be verified.
