`WP_User_Query` role improvement redux. 

It's back, and it's better than ever: an overhaul of role-related arguments
in `WP_User_Query`. This updated version of the previously-reverted [34875]
includes support for the use of `$blog_id` without specifying a `$role`, for
a 99.7% reduced chance of breaking wordpress.org and other large sites.

Props boonebgorges, swissspidy.
Fixes #22212.
Built from https://develop.svn.wordpress.org/trunk@34959
