/**
 * Parses and extracts the namespace and reference path from the given
 * directive attribute value.
 *
 * If the value doesn't contain an explicit namespace, it returns the
 * default one. If the value contains a JSON object instead of a reference
 * path, the function tries to parse it and return the resulting array. If
 * the value contains strings that represent booleans ("true" and "false"),
 * numbers ("1" and "1.2") or "null", the function also transform them to
 * regular booleans, numbers and `null`.
 *
 * Example:
 *
 *     extract_directive_value( 'actions.foo', 'myPlugin' )                      => array( 'myPlugin', 'actions.foo' )
 *     extract_directive_value( 'otherPlugin::actions.foo', 'myPlugin' )         => array( 'otherPlugin', 'actions.foo' )
 *     extract_directive_value( '{ "isOpen": false }', 'myPlugin' )              => array( 'myPlugin', array( 'isOpen' => false ) )
 *     extract_directive_value( 'otherPlugin::{ "isOpen": false }', 'myPlugin' ) => array( 'otherPlugin', array( 'isOpen' => false ) )
 *
 * @since 6.5.0
 *
 * @param string|true $directive_value   The directive attribute value. It can be `true` when it's a boolean
 *                                       attribute.
 * @param string|null $default_namespace Optional. The default namespace if none is explicitly defined.
 * @return array An array containing the namespace in the first item and the JSON, the reference path, or null on the
 *               second item.
