Options, Meta APIs: Fast follow fixes for option cache priming functions.

Browse Source 
A collection of fixes for `wp_prime_option_caches()`:

* cache arrays and objects in their serialized form for consistency with `get_option()` and `wp_load_alloptions()`
* prevent repeat database queries for falsey and known non-existent options (notoptions)

Additional tests for `wp_prime_option_caches()` to ensure:

* additional database queries are not made repriming options (known, known-unknown and alloptions)
* cache is primed consistently
* `get_option()` returns a consistent value regardless of how it is primed
* database queries do not contain earlier primed options
* `get_option` does not prime the cache when testing the cache has been successfully primed

Fixes a test for `wp_prime_option_caches_by_group()` to ensure `get_option` does not prime the cache when testing the cache has been successfully primed.
