Evaluate moving all NodeType and NodeTypeFields persistance to stateless and static configuration files

[ambroisemaupate]

Today Roadiz store its node-type and node-type-fields in 3 different locations:

• node_type and node_type_field database tables
• NSXxxxXxxx generated node-source entity
• src/Resources/config/XxxxxXxxx.json node-type definition file for migration between environments

This leads into migration issues between developer inside the same project, and between local and remote environments.

We should evaluate removing node-type and fields from database and only load these data from static files to :

• render NodeSource forms
• generate NSXxxxxXxxx PHP files
• generate Doctrine migration on NodeSource table
• Switch from JSON to YAML for NodeType declaration files and stick to Symfony style
• Keep an administrable Decoration system to alter node-type and node-type-field properties for non-dev users
• etc

REopened, we have to generate the last migration to remove NodeType table

@ambroisemaupate We need to do a backport on version 2.4 of the command to export the node types to file, add the associated serialization groups and add the mention of depreacated on the method and useless file.
