#23330: Allow autoloading all options, not just autoload = yes options

For 5 years on wordpress.com we have ignore the autoload field for
options. In wp_load_alloptions(), autoload = yes is not part of the query.
Why? Because wordpress.com has a persistent cache. Thus, the transients
that constitute the bulk of autoload = no options are stored in cache,
never in the options table. Querying autoload=yes makes the query slower
for no reason.
Having autoload = no options also complicates notoptions caching. Core has
a notoptions cache that would be unnecessary if you can assume that
wp_load_alloptions() loads every option. If an option is not in
alloptions, then it does not exist.
Other large sites that use a persistent cache might also like to ignore
the autoload flag. Core could automatically switch to ignoring autoload
when an external object cache is being used, but administrators might want
to control this so they can clean out old transients from options tables
and do whatever other housekeeping is desired. So, let's add a filter that
allows toggling this. When autoload is being ignored the
wp_load_alloptions() query does not include autoload=yes and notoptions is
not used.
