Query: Use `WP_Query` in `get_page_by_path`. 

Replace raw database queries in `get_page_by_path` with a call to `WP_Query` class. This has a number of benefits, including improved caching and priming of post caches. To maintain backwards compatibility, this function calls `WP_Query` to gets all matching posts of all post statuses.  

Props spacedmonkey, peterwilsoncc, costdev,
