* Returns the data merged from multiple origins.
*
* There are four sources of data (origins) for a site:
*
* - default => WordPress
* - blocks => each one of the blocks provides data for itself
* - theme => the active theme
* - custom => data provided by the user
*
* The custom's has higher priority than the theme's, the theme's higher than blocks',
* and block's higher than default's.
*
* Unlike the getters
* {@link https://developer.wordpress.org/reference/classes/wp_theme_json_resolver/get_core_data/ get_core_data},
* {@link https://developer.wordpress.org/reference/classes/wp_theme_json_resolver/get_theme_data/ get_theme_data},
* and {@link https://developer.wordpress.org/reference/classes/wp_theme_json_resolver/get_user_data/ get_user_data},
* this method returns data after it has been merged with the previous origins.
* This means that if the same piece of data is declared in different origins
* (default, blocks, theme, custom), the last origin overrides the previous.
*
* For example, if the user has set a background color
* for the paragraph block, and the theme has done it as well,
* the user preference wins.
*
* @since 5.8.0
* @since 5.9.0 Added user data, removed the `$settings` parameter,
* added the `$origin` parameter.
* @since 6.1.0 Added block data and generation of spacingSizes array.
* @since 6.2.0 Changed ' $origin' parameter values to 'default', 'blocks', 'theme' or 'custom'.
*
* @param string $origin Optional. To what level should we merge data: 'default', 'blocks', 'theme' or 'custom'.
* 'custom' is used as default value as well as fallback value if the origin is unknown.
