Render elements can use dependency injection

[el7cosmos]

Bug report

Render elements should be able to use dependency injection, but \Drupal global is allowed in render elements in this following rule:

phpstan-drupal/src/Rules/Drupal/GlobalDrupalDependencyInjectionRule.php

Lines 43 to 45 in d30fbd7

	// Render elements cannot use dependency injection.
	'Drupal\Core\Render\Element\ElementInterface',
	'Drupal\Core\Render\Element\FormElementInterface',

Looks like ElementInfoManager does support ContainerFactory now!
