Registers _wp_cron() to run on the {@see 'shutdown'} action.
The spawn_cron() function attempts to make a non-blocking loopback request towp-cron.php
(when alternative
cron is not being used). However, the wp_remote_post() function does not always respect the timeout
and
blocking
parameters. A timeout of 0.01
may end up taking 1 second. When this runs at the {@see 'wp_loaded'}
action, it increases the Time To First Byte (TTFB) since the HTML cannot be sent while waiting for the cron request
to initiate. Moving the spawning of cron to the {@see 'shutdown'} hook allows for the server to flush the HTML document to
the browser while waiting for the request.
