Multisite: Add the `pre_get_blogs_of_user` filter
This allows a plugin to short circuit `get_blogs_of_user()` in cases where the default behavior of the function is unnecessary or slow. (e.g. A user is a member of thousands of sites.) Props jsternberg. See #31746, Fixes #36707. git-svn-id: https://develop.svn.wordpress.org/trunk@37326 602fd350-edb4-49c9-b593-d223f7449a82
