Fix dependencies in the various content block content types.

• Change the following modules to explicitly reference cgov_embedded_block as a dependency:
  • cgov_content_block
  • cgov_image
  • cgov_site_section
  • cgov_video
• Move the field definition for field_youtube_playlist_id from cgov_content_block to cgov_video.
