Additional/fixed tests for 58962.

[peterwilsoncc]

See https://core.trac.wordpress.org/ticket/58962

Some additional tests that already pass.

These can be committed and back-ported during the release candidate phase as they do not touch source code.

Commit message draft:

Options, Meta APIs: Improve tests for option cache priming.

Improves a number of tests for the `wp_prime_option_caches()` function to ensure:

* `get_option()` does not prime the cache while testing the function has primed the cache
* it handles a mix of primed, unprimed and non-existent options
* passing an empty array doesn't trigger a DB query
* `get_option()` returns the same value regardless of how the cache is primed
* re-priming the cache does not trigger additional DB calls (at present this only tests truthy values pending #59738)
* re-priming items primed by `wp_load_alloptions()` does not trigger additional DB calls

Additionally, ensures  `get_option()` does not prime the cache while testing `wp_prime_option_caches()` has primed the cache.

@peterwilsoncc Is there anything in here that's not in #5576? I'm asking since I think we should rather commit that PR with the fixes and backport it, per my response on the ticket.

All of these are in the other pr. I agree, it’s best to put the other pr in but wanted to pull out these so I had passing tests I could yolo commit during the rc if the src changes weren’t approved. --Sent from my phoneOn 31 Oct 2023, at 5:01 am, Felix Arntz ***@***.***> wrote: @felixarntz commented on this pull request. @peterwilsoncc Is there anything in here that's not in #5576?
