/**
* @covers ::build
*
* MenuLinkTree::build() gathers both:
* 1. the tree's access cacheability: the cacheability of the access result
* of checking a link in a menu tree's access. Callers can opt out of
* this by MenuLinkTreeElement::access to NULL (the default) value, in
* which case the menu link is always visible. Only when an
* AccessResultInterface object is specified, we gather this cacheability
* metadata.
* This means there are three cases:
* a. no access result (NULL): menu link is visible
* b. AccessResultInterface object that is allowed: menu link is visible
* c. AccessResultInterface object that is not allowed: menu link is
* invisible, but cacheability metadata is still applicable
* 2. the tree's menu links' cacheability: the cacheability of a menu link
* itself, because it may be dynamic. For this reason, MenuLinkInterface
* extends CacheableDependencyInterface. It allows any menu link plugin to
* mark itself as uncacheable (max-age=0) or dynamic (by specifying cache
* tags and/or contexts), to indicate the extent of dynamism.
* This means there are two cases:
* a. permanently cacheable, no cache tags, no cache contexts
* b. anything else: non-permanently cacheable, and/or cache tags, and/or
* cache contexts.
*
* Finally, there are four important shapes of trees, all of which we want to
* test:
* 1. the empty tree
* 2. a single-element tree
* 3. a single-level tree (>1 element; just 1 element is case 2)
* 4. a multi-level tree
*
* The associated data provider aims to test the handling of both of these
* types of cacheability, and for all four tree shapes, for each of the types
* of values for the two types of cacheability.
*
* There is another level of cacheability involved when actually rendering
* built menu trees (i.e. when invoking RendererInterface::render() on the
* return value of MenuLinkTreeInterface::build()): the cacheability of the
* generated URLs.
* Fortunately, that doesn't need additional test coverage here because that
* cacheability is handled at the level of the Renderer (i.e. menu.html.twig
* template's link() function invocation). It also has its own test coverage.
*
* @see \Drupal\menu_link_content\Tests\MenuLinkContentCacheabilityBubblingTest
