The content_translation_translate_access() and _content_translation_install_field_storage_definitions() functions are deprecated

The content_translation_translate_access() function is deprecated and its logic was moved in the content_translation.manager service as a new ::access() method.

Before

$comment = \Drupal\comment\Entity\Comment::load(123);

if (content_translation_translate_access($comment)) {
  // Do something...
}

...

_content_translation_install_field_storage_definitions($settings->getTargetEntityTypeId());

After

$comment = \Drupal\comment\Entity\Comment::load(123);

// In a real case scenario properly inject the content_translation.manager service.
if (\Drupal::service('content_translation.manager')->access($comment)) {
  // Do something...
}

...

$this->installFieldStorageDefinitions($settings->getTargetEntityTypeId());

The protected method \Drupal\comment\CommentLazyBuilders::access(), which was only a wrapper around content_translation_translate_access() was also deprecated.
