Themes: Make block themes support HTML5 by default.

For block themes, [52369] added HTML5 support for `'comment-list'`, `'comment-form'`, `'style'`, and `'script'`. However, when sites upgrade to 5.9 with non-block content such as a gallery and caption, the markup was not HTML5. 

This commit adds full HTML5 theme feature support for block themes. Non-block content such as a `[gallery]` and `[caption]` shortcodes will natively be in HMTL5 markup without block themes needing to specifically add `add_theme_support( 'html5, .. )` to the theme. 

Follow-up to [24417], [27302], [34261], [52369], [52383], [52386].
