Calculate dependencies should include block dependencies

Problem/Motivation

Calculate dependencies should include block dependencies.

e.g. from LayoutBuilderEntityViewDisplay:

  public function calculateDependencies() {
    parent::calculateDependencies();

    foreach ($this->getSections() as $section) {
      $this->calculatePluginDependencies($section->getLayout());
      foreach ($section->getComponents() as $component) {
        $this->calculatePluginDependencies($component->getPlugin());
      }
    }

    return $this;
  }

Steps to reproduce

Add a block provided by a module and export config.
The dependency is not there.

Proposed resolution

We should include dependencies.

Remaining tasks

Fix and test.

User interface changes

None.

API changes

Data model changes
