Add database migration for disabling autoload for our options

[swissspidy]

Task Description

Noticed while reviewing #13700.

On my local site our options were all autoloaded for some reason. They shouldn't be; especially when we do the cache priming.

We could add a database migration that runs once to call wp_set_options_autoload() for all our options to disable autoloading.

Not sure if it's really needed though and whether it's worth it.

Also: the function is only available in WP 6.4+

Hi @swissspidy, should we get started with this since we have bumped up WP version requirement to 6.4?
