Tiled Gallery Block: remove Plans dependency for VIP Support

[jeherve]

Follow-up to #13293

Proposed changes:

Instead of relying on a WordPress.com API request to get the site's plan, and thus to figure out whether the site is on VIP or not, let's rely on the site's constants. That will save us an external request, and will allow to more easily extract the Tiled Gallery block in the future if necessary.

Other information:

• Have you written new tests for your changes, if applicable?
• Have you checked the E2E test CI results, and verified that your changes do not break them?
• Have you tested your changes on WordPress.com, if applicable (if so, you'll see a generated comment below with a script to run)?

Testing instructions:

Note

This would need to be tested on the VIP platform.

1. Go to Posts > Add New
2. Add a Tiled Gallery block
3. View the post on the frontend, ensure the images are properly displayed and do not use the Photon subdomain i*.wp.com.

@mikeyarce I'm not quite sure how I can spin up a VIP site with this patch to test this. Is there anyway you could help with that and test this patch on one of your sandboxes?

Thank you!

Are you an Automattician? Please test your changes on all WordPress.com environments to help mitigate accidental explosions.

• To test on WoA, go to the Plugins menu on a WordPress.com Simple site. Click on the "Upload" button and follow the upgrade flow to be able to upload, install, and activate the Jetpack Beta plugin. Once the plugin is active, go to Jetpack > Jetpack Beta, select your plugin, and enable the update/tiled-gallery-plan-dependency branch.

• To test on Simple, run the following command on your sandbox:

  bin/jetpack-downloader test jetpack update/tiled-gallery-plan-dependency
