Improve eval_which_host()

protected function eval_which_host( \stdClass $site ): string {

The current approach in this function:

1. uses the is_wpcom_atomic field returned by the wpcom /me/sites API endpoint. Note, that field is actually returned twice when calling "https://opsoasis.wpspecialprojects.com/wp-json/wpcomsp/wpcom/v1/sites/team51.blog/", once at the root and once in the options element.
2. If the site is Jetpack, using the jetpack element from the wpcom /me/sites API endpoint...
   a. checks if the site url is in the list of pressable sites which comes from get_pressable_sites()
   b. Makes a remote request to check the /.well-known/hosting-provider and looks for "Pressable", otherwise defaults Jetpack sites to "Other"
3. Otherwise assumes WP.com Simple

Suggest improvements:

• finish the TODO to check for "wpvip.com" in the well known hosting provider section
• I think we can identify WP.com Simple sites by looking for "wordpress.com" in the value of options.unmapped_url in the response from wpcom /me/sites API endpoint

cc: @cagrimmett if we get these done, I think we can use the results of this command as the starting point for our "who pays for what" work
