This task is part of the effort to rework the Starter Page Template Picker for new pages. This part of the initiative will focus on modifying the API call /wpcom/v2/sites/{site}/block-layouts to include the supported_blocks
query parameter which will be used to only include layouts that have met a server defined threshold of supported blocks.

Goals

• Create a mechanism that takes exposes the same array of coreBlocks defined in Gutenberg and exposes those to the App.
  • For now, this can be as simple as duplicating the list in coreBlocks to the apps.
  • Ideally this would be a mechanism that would be shared by the block registration as well as the list passed to the apps but that can be separated out to a future enhancement.
• Use this array to modify the API call /wpcom/v2/sites/{site}/block-layouts with the query paramert supported_blocks that was developed as part of Filtering of templates based on the supported blocks #2415
