This reverts commit d1f7bd97cb989d8d98e009ef71a72c7cac5077dd.
Ryan pointed out that this needs to work with the multi term query, so
additional analysis and tests should be added.
The analysis chain should be used instead of relying on this, as it is
confusing when dealing with different per-field analysers.
The `locale` option was only used for `lowercase_expanded_terms`, which,
once removed, is no longer needed, so it was removed as well.
Fixes#9978
Relates to #9973
