Subject: [PATCH] Options, Meta APIs: Prime transient options prior to use.

Reduce the number of queries getting and setting transients on sites without a persistent cache.

Transients are stored in two options: one each for the transient value and timeout. Priming the cache reduces the database queries for getting a transient from two to one.

Props peterwilsoncc, swissspidy.
Fixes #61193.
