Message:

Options, Meta APIs: Fix bug with update_option() updating the wrong cache, leading to potentially stale values being returned.

When using the $autoload parameter of update_option() alongside an option value update, prior to this changeset the function would update the incorrect cache, not respecting the new autoload value. This could have severe implications such as returning a stale option value when the option in fact had already been deleted.

This changeset fixes the bug alongside test coverage that failed with trunk but now passes.

Props kkmuffme, pentatonicfunk, SergeyBiryukov, oglekler, azaozz, spacedmonkey, nicolefurlan, joemcgill, flixos90.
Fixes #51352.
