Comment:

 The patch adds the support for the {{{paged}}} argument in
 {{{WP_Site_Query}}} and {{{WP_Network_Query}}}.

 It's similar to the approach in #38268, for the {{{WP_Comment_Query}}},
 but I took a different approach in the tests. I tried to re-use the setup
 in:

 - {{{Tests_Multisite_Site_Query::wpSetUpBeforeClass()}}} and
 - {{{Tests_Multisite_Network_Query::wpSetUpBeforeClass()}}},

 using {{{get_site_by()}}} and {{{get_network_by()}}}. I will have to look
 better into that, if that's ok.

 This patch also takes care of a previous problem with {{{paged}}} as 0,
 where the previous generated SQL query would contain a negative start
 value in the LIMIT clause.  When it's 0 it's treated as the default value
 of 1.
