Coding Standards: Simplify the logic for setting DB host and port in wpdb::parse_db_host()
.
This removes an extra `foreach` loop and the only variable variable (`$$component`) in core. Follow-up to [20088,28342,28736-28747], [41629], [41820], [42226], [53670]. Props johnjamesjacoby. See #54877, #55647. Built from https://develop.svn.wordpress.org/trunk@53671 git-svn-id: http://core.svn.wordpress.org/trunk@53230 1a063a9b-81f0-0310-95a4-ce76da25c4cd
