Improved 'orderby' meta syntax in `WP_User_Query`.

Recent commits have added the ability to order query results by specific
clauses of the 'meta_query' parameter (comments [31467], posts [31312] and
[31340]). The current changeset ports the same functionality to `WP_User_Query`.

Also introduced is the ability to pass the value of `$meta_key` to 'orderby'.

The internals of `WP_User_Query::prepare_users()` had to be reordered
somewhat to support these changes, primarily to ensure that the `meta_query`
object generates its SQL clauses before the 'orderby' parameter is parsed.

See #31265.
