Tests: Add unit tests for theme features that block themes should support by default.

Browse Source 
By default, block themes should have a few theme supports enabled:
* `post-thumbnails`
* `responsive-embeds`
* `editor-styles`
* `html5` for `comment-form`, `comment-list`, `style`, `script`
* `automatic-feed-links`

They should also load core block assets only when the blocks are rendered. This commit adds the associated tests.

Follow-up to [52369].

Props costdev.
See #54597.
