Fixes bug where an invalid Last-Modified value would be returned in feed requests for sites that had 0 items to return. Comment or post feeds will now return the current timestamp as the Last-Modified header value. Example: a request for the comments feed for a site without any comments. Replaced use of the local static variable `$cache_lastcommentmodified` to store the modified date in `get_lastcommentmodified()` with the Object Cache API. The `get_lastcommentmodified()` function returns early if there is a cached value and returns `false` if there where no comments found. Introduced `_clear_modified_cache_on_transition_comment_status()` to flush the `lastcommentmodified` cache key when a comment enters or leaves approval status. In `get_lastpostmodified()` return early if there is a cached value and return `false` if there are no posts found. Props swissspidy, rachelbaker, dllh, leobaiano. Fixes #38027.
