Add WP.com simple site and Jetpack site routing to WpApiClient

[jkmassel]

Summary

• WP.com simple site URL routing: Add isWPComSimpleSite() to SiteModel and override getWpApiRestUrl() to return the public-api.wordpress.com proxy URL for simple (non-Atomic) WP.com sites
• Jetpack site routing: Route sites using the WP.com REST API (isUsingWpComRestApi) through the WP.com API client alongside pure WP.com sites
• Migrate to new apiUrlResolver constructor: Update createSelfHostedClient to use WpOrgSiteApiUrlResolver instead of the old wpOrgSiteApiRootUrl parameter

Test plan

• Verify WP.com simple sites get the correct public-api proxy URL from getWpApiRestUrl()
• Verify Jetpack-connected sites route through the WP.com API client
• Verify self-hosted sites continue to use application password auth and WpOrgSiteApiUrlResolver

@jkmassel There are multiple conflicts and CI failures in this PR. Probably best to address that before I do a review.
