Remove block.module dependency from Layout Builder

Problem/Motivation

\Drupal\Core\Block provides the entire block plugin system.
block.module provides the Block UI (admin/structure/block) used to place instances of those block plugins into theme regions

layout_builder.module uses block plugins as well, but has nothing to do with theme regions or per-theme block placements.

Yet it has a hard dependency on block.module for (at least) two reasons:

  1. It uses '#theme' => 'block' for it's output, which is provided by block.module instead of by system.module
  2. While waiting for #2936655: Layout Builder should use the toolbar modes system once it exists. → , Layout Builder adopted local tasks for navigation, which are provided by a theme-based block

Proposed resolution

Move the block template and theme hook from block.module to system.module
Wait for a non-local-task based approach for navigation

Remaining tasks

Restore block.html.twig in Block module but with a deprecation

User interface changes

API changes

Data model changes
