Query: Allow the hyphen-prefix-for-search-exclusion feature to be disabled by filter.

Browse Source 
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.

Props chriseverson, choongsavvii.
Fixes #38099.
Built from https://develop.svn.wordpress.org/trunk@38792
