[38792] allowed `WP_Query`'s hyphen-as-exclusion-prefix feature to be
disabled via filter. A more general solution is to allow the prefix to
be filtered; returning an empty value from a filter callback works to
disable the feature.
Props dlh.
Fixes#38099.

WordPress 4.4 introduced "hyphen exclusion" for search terms, so that
"foo -bar" would return posts containing "foo" AND not containing "bar".
The new filter 'wp_query_use_hyphen_for_exclusion' allows developers
to disable this feature when it's known that their content will contain
semantically important leading hyphens.

Hiding the `$wpdb` global behind a property decreases the readability of the code, as well as causing irrelevant output when dumping an object.

The refactor in [30711] swapped out the old `queries` property for the
new `queried_terms`, but should also have gotten rid of the now-
superfluous `wp_list_filter()` call.
