Fixes #280, fixes #277 Remove Layout Builder Customizations

[tadean]

This PR removes our Layout Builder customizations and replaces them with a placeholder paragraph reference field to prepare for our transition to paragraphs.

Description

Configuration related to our Layout Builder customizations has been removed, paragraphs has been added, and the Page content type has been given a paragraph reference field in order to provide a placeholder for our paragraphs implementations.

Since removing the Layout Builder customizations effectively leaves Page without any way to add content, a simple placeholder paragraph bundle has been added (az_text).

This placeholder implementation follows the same pattern as the D7 implementation: az_content_chunks contains the modules related to the paragraph bundles, and the individual paragraph bundles are submodules inside it, in this case az_content_chunks_text.

The placeholder az_content_chunks module provides library loading functionality such as we originally had on our inline blocks for Layout Builder (ie. it's possible to load CSS and JS for a specific paragraph bundle.) The placeholder az_text bundle has a CSS file defined, not because it's necessary, but just to demonstrate the functionality for furture work.

Display Suite has been removed as it was no longer required for anything, which fixes #277

Flexible pages will have paragraphs available only for the az_content_chunks submodules that are currently enabled.

A test should ideally be added before merging, as there used to be one present in the layout builder customizations.

Looks like the Deprecated Code check failures are all due to classes extending base classes provided by modules that we don't include in Quickstart. I'm assuming the Entity Reference Revisions and Paragraphs module classes provide optional functionality that is only available if the modules providing the base classes are installed but do you think we should consider adding any of these modules?

• Entity Browser

I think I like all of those modules.

I'd be open to including those if it squelches the warnings, they all seem like pretty useful utility modules in general to have in our toolkit.

Hey Troy how do you feel about using an object oriented approach to preprocessing paragraphs, as seen in the attached module?
az_components.zip

I like it! I'll update to do something similar.

Updated with D9 changes from master.

feeds and entity_browser both have their own deprecation warnings when they're added to the build to attempt to solve the deprecation warnings. FWIW, feeds doesn't have a stable release yet, either. I'll look into if maybe there are any patches floating around that solve the original issues.

• Added basic unit test
• Switched preprocessing of paragraphs to being in a Drupal service per @trackleft 's suggestion.

Updated pull request to change the name of az_content_chunks to az_paragraphs.

Updated to change the label of the text area of the placeholder paragraph from AZ Text Area to Text.

Updated to change the description/name of the placeholder paragraph bundle module from Plain Text to Text, to support the requirements of the proposed final Text paragraph.

Per 2020-09-09 PR meeting & 2020-09-11 Friday meeting: new deprecation warnings will be addressed in followup issue.
