Add a way to programmatically generate bundle list cache tags

Problem/Motivation

IMHO it is a good practice to not hardcode cache tags in custom code and instead generate them programmatically.
For example, when writing a render array that varies when a node is added or removed, it is possible to use EntityType::getListCacheTags (and EntityType::getListCacheContexts) to generate the appropriate node_list tag.

Since #2145751: Introduce ENTITY_TYPE_list:BUNDLE cache tag and add it to single bundle listing we have a ENTITY_TYPE_list:BUNDLE cache tag but no way to generate it programmatically.

Steps to reproduce

$cache = new CacheableMetadata();

// I can add node_list programmatically:
$cache->addCacheTags(\Drupal::entityTypeManager()->getDefinition('node')->getListCacheTags());
$cache->addCacheContexts(\Drupal::entityTypeManager()->getDefinition('node')->getListCacheContexts());

// But if I only care about a single bundle, I have to know the tag name:
$cache->addCacheTags(['node_list:' . $bundle]);

Proposed resolution

Maybe something like this:

\Drupal::entityTypeManager()->getDefinition('node')->getBundleListCacheTags('mybundle');

Remaining tasks

User interface changes

Introduced terminology

API changes

Developers can use the new EntityType::getBundleListCacheTags() method to generate the appropriate cache tags if we want a cached element to be invalidated when a node of a specific bundle is updated, deleted or added.

Data model changes
