Prepare for WPVIP: Use VIP activation procedure

[moorscode]

register_activation_hook and register_deactivation_hook are not supported because of the way plugins are loaded on WordPress VIP using wpcom_vip_load_plugin.

See: https://vip.wordpress.com/documentation/code-review-what-we-look-for/#plugin-registration-hooks

The documentation is not clear on how to implement a way that will work.
This should be determined.

Probably abundant but: note that these hooks must still remain to work for non-VIP installations.

Hey @moorscode. I work for a company who hosts sites on VIP. We're always getting requests for adding Yoast to our writers' toolset. Any idea when this would be available as a VIP approved plugin? We'd love to use it in our theme! Is it just waiting on a PR fixing some of the compliance needs?

Any updates on this one?

I've been using wpcom_vip_load_plugin( 'wordpress-seo/wp-seo.php' ); with mixed success... works on one site, but not on another VIP Go site.
