Dependency injection in permission callbacks

Problem/Motivation

The permissions callback provider class, being handled by the controller resolver, is capable of dependency injection by implementing ContainerInjectionInterface. The following patch adds that for the node module permission provider. The same should be done for other core modules that provide permission callbacks.

Proposed resolution

Make NodePermissions implement ContainerInjectionInterface
Add autowiring of entity type manager

Remaining tasks

Review

API changes

NodePermissions now requires an $entityTypeManager argument.
