Problem/Motivation
The node add page (node_add_list) and the block content add page block_content_add_list are using standalone theme (and template) for theming their page content.
Drupal provides the entity_add_list theme function for this since #2666792: Provide a route provider for add-page of entities is in. This is used by Media module in core.
Proposed resolution
Remove node_add_list and block_content_add_list theme functions and use entity_add_list instead of them.

berdirAnd I think #2723579: NodeRouteProvider should extend DefaultHtmlRouteProvider should take care of the node_list_add template, although it doesn't yet. closing as duplicate of those two.

avpaderno#2723579: NodeRouteProvider should extend DefaultHtmlRouteProvider has not unified the templates used for pages listing the entity bundles which can be created.
