Pascal Birchler de5181d97b Multisite: Handle sites cache invalidation more granularly for option updates.
Previously `update_blog_option()` would trigger an invalidation of that site's entire cache although these changes did not affect the content of 
these caches. Furthermore changes to the special options `blogname`, `siteurl` and `post_count` should not invalidate the entire cache of that site, but only their respective site details cache. The option `home` now has the same behavior as it also belongs to the site details, but did not invalidate the cache at all previously.

Several new unit tests confirm these changes work as expected.

Fixes #40063.

Merges [40305] and [40333] to the 4.7 branch.
