Aaron Jorbin a8aa7b0ca2 Cache API: introduce wp_cache_get_last_changed to improve DRY
One thing fairly common to the cache groups is a block of code to look to see when the cache was last changed, and if there isn't one, to set it for the current microtime(). It appears in 8 different places in core. This adds a new helper `wp_cache_get_last_changed` to DRY things up a bit.

Since `wp-includes/cache.php` isn't guaranteed to be loaded, this new function is in `wp-includes/functions.php`

Props spacedmonkey, desrosj.
Fixes #37464.
