Section styles: improve performance and conceptual consistency.

Browse Source 
These changes involve:

- Move shared variation definitions from styles.blocks.variations to styles.variations
- Remove blockTypes from styles.variations.
- Do not register shared variations from theme style variation or primary theme.json files.
- Move the merging of theme.json data into the WP_Theme_JSON_Resolver and WP_Theme_JSON classes.

These changes improve performance and are more future-proof API wise.
