Multisite: Clear incomplete objects from cache in `get_blog_details()` when found. 

In [37657], the `blog_id` and `site_id` properties were changed to private. Any `WP_Site` objects previously stored in cache with public properties should now be considered invalid. We can detect this by checking for these missing properties and clearing the dirty cache if found.

Props flixos90.
Fixes #36717.
