Deprecate node_revision_load() and friends

Problem/Motivation

Spotted in a test over in #3319582: Fix calls to methods with too many parameters passed in, we deprecated and removed node_load() a long time ago but the following functions still exist in node.module:

function node_revision_load($vid = NULL) {
  return \Drupal::entityTypeManager()->getStorage('node')->loadRevision($vid);
}

function node_revision_delete($revision_id) {
  \Drupal::entityTypeManager()->getStorage('node')->deleteRevision($revision_id);
}

function node_type_update_nodes($old_id, $new_id) {
  return \Drupal::entityTypeManager()->getStorage('node')->updateType($old_id, $new_id);
}

Steps to reproduce

Proposed resolution

Deprecate these functions and use the entity storage methods in preference.

Remaining tasks

User interface changes

API changes

Data model changes
