Multisite: Implement the `get_by_path` method in `WP_Network`.
Move the internals of `get_network_by_path()` to `WP_Network()` and allow network objects to be retrieved by passing a requested domain and path. Props johnjamesjacoby, jeremyfelt, drewapicture, wonderboymusic. See #31985. Built from https://develop.svn.wordpress.org/trunk@34099 git-svn-id: http://core.svn.wordpress.org/trunk@34067 1a063a9b-81f0-0310-95a4-ce76da25c4cd
