Add wp option get-autoload and wp option set-autoload

[danielbachhuber]

Adds wp option get-autoload and wp option set-autoload commands:

$ wp option add foo bar
Success: Added 'foo' option.
$ wp option get-autoload foo
yes
$ wp option set-autoload foo no
Success: Updated autoload value for 'foo' option.
$ wp option set-autoload foo no
Success: Autoload value passed for 'foo' option is unchanged.

These are useful for manipulating the autoload value. wp option update can't be used for this directly because update_option() won't change autoload if the value doesn't change.

Recreates the cache manipulation inside of update_option() too: https://github.com/WordPress/wordpress-develop/blob/04e8bb4bb5ed37dade1b1ddda634e45f7503820d/src/wp-includes/option.php#L525-L540

This feels brittle, but not sure there's a better way around it...

This means the API is:

wp option set-autoload my_option no

That seems to be forced by the DB value and is neither developer-speak (set autoload true) nor natural language (disable autoload).

I'm don't love that API, but I have trouble coming up with something better.

What do think about:

wp option autoload get my_option
wp option autoload enable my_option
wp option autoload disable my_option

@schlessera Good points. I don't love your proposed approach either because it seems unnecessarily complex to nest the commands further.

I went with wp option set-autoload my_option no because wp option add accepts --autoload=yes/--autoload=no.
