Query: Save excessive cache add and sets in `WP_Query`.
In [53941] database query caching was added to `WP_Query`. However on
sites with persistent object caching enabled, this resulted in a high
number of unnecessary cache set and adds being run on every request.
Caches are not set, if the query cache already exists and is cached.
Replace usage of `update_post_caches` with `_prime_post_caches` to ensure
that only posts that are not in cache are primed.
Props spacedmonkey, peterwilsoncc, mukesh27.
See #22176.
