Options, Meta APIs: Explicitly pass $autoload parameter to when potentially adding new options.
It is recommended that for every option it is explicitly set whether to autoload it or not. This changeset updates relevant update_option() and add_option() calls.
Note that the $autoload parameter is only needed for update_option() if the option is potentially not present yet, i.e. the call will pass through to add_option(). Since WordPress core adds the majority of its options to the database during installation, only update_option() calls for dynamically added options need to be modified, which is what this changeset does.
As part of revisiting the autoload values for dynamically added WordPress core options, this changeset modifies some options to no longer be autoloaded, since they are only accessed in a few specific places that are not relevant for a regular request. These options are:
recently_activated
_wp_suggested_policy_text_has_changed
{upgradeLock}.lock
dashboard_widget_options
ftp_credentials
adminhash
nav_menu_options
wp_force_deactivated_plugins
delete_blog_hash
allowedthemes
{sessionId}_paused_extensions
recovery_keys
https_detection_errors
fresh_site
An upgrade routine is present as well that sets those options to no longer autoload for existing sites.
