Adjust caching logic of LayoutBuilderAccessCheck::access()

Problem/Motivation

The logic of RefinableCacheableDependencyTrait::addCacheableDependency() has been updated in #3232018: Trigger a deprecation when using \Drupal\Core\Cache\RefinableCacheableDependencyTrait::addCacheableDependency with a non CacheableDependencyInterface object.

If the passed object is NOT an instance of CacheableDependencyInterface
Previous behavior: max-age is set to 0
Future behavior: an exception is thrown

In order to get rid of the deprecation notice and preserve the old behavior, one bit of LayoutBuilderAccessCheck::access() code was changed from

$access->addCacheableDependency($section_storage);

to

if ($section_storage instanceof CacheableDependencyInterface) {
  $access->addCacheableDependency($section_storage);
}
else {
  $access->setCacheMaxAge(0);
}

However, it was noticed that SimpleConfigSectionStorage is the only class that does not implement CacheableDependencyInterface.

Maybe SimpleConfigSectionStorage should be extended to implement CacheableDependencyInterface? Then the if condition could be removed.
