Reuse site objects in MS user and site list tables rather than calling get_blog_status()

[jeremyfelt]

In class-wp-ms-users-list-table.php and class-wp-ms-sites-list-table.php, we loop through sites and use get_blog_status() to determine if each is archived, spam, mature, or deleted.

As highlighted in #32281, this data is available from the database as part of the site object and can be reused.

32512.diff

• Removes uses of get_blog_status() from both the sites and users MS list table.
• Adds mature as a property when retrieving site objects from get_blogs_of_users().

Core's only other use of get_blog_status() is in is_archived(), which we may be able to deprecate.

In 32630:

Use site objects rather than get_blog_status() in MS list tables.

Removes several repetitive calls to get_blog_status() that are not needed, as the data is already available as part of each site's object.

Fixes #32512.
