[1.0.0-alpha2] Display Builder availability according to roles or permissions

Jean's notes:

Have dynamic config available to the instanciation of display builder `stateManager::create()` and to the user using the display builder.
So config should be permission based. Each config have a `use` permission.

Implementation

For each instance associated with entity / page / views we should store a default config, when using `stateManager::create()` with fallback to default.
This value is stored as `entity_config_id` on the storage, it's a default value for this display builder.

Display builder UX

Have a switch of display builder config when on a display builder, only available the one with current user permission and default to the default one set in state storage `entity_config_id`.

DB config, one global permission 'administer display builders' to create / edit Delete
For each DB config, one usage permission (as filter module):
Use the %name Display builder config

Filter module permissions, for information:

administer filters:
  title: 'Administer text formats and filters'
  description: 'Define how text is handled by combining filters into text formats.'
  restrict access: true

permission_callbacks:
  - Drupal\filter\FilterPermissions::permissions

I start it, as a follow-up of 📌 Align config storage properties Active .

What do you think about the logic in ConfigFormTrait::buildConfigForm()

    return match (count($options)) {
      0 => [
        '#type' => 'html_tag',
        '#tag' => 'p',
        '#value' => t('You are not allowed to use Display Builder.'),
      ],
      1 => [
        '#type' => 'hidden',
        '#default_value' => array_keys($options)[0],
      ],
      default => [
        '#type' => 'select',
        '#title' => $this->t('Display builder config'),
        '#options' => $options,
        '#default_value' => $display_builder,
      ]
    };

It was not discussed.

Jean's proposal:

    return match (count($options)) {
      0 => [
        '#type' => 'hidden',
        '#default_value' => array_keys($options)[0],
      ],
      1 => [
        '#type' => 'hidden',
        '#default_value' => array_keys($options)[0],
      ],
      default => [
        '#type' => 'select',
        '#title' => $this->t('Display builder config'),
        '#options' => $options,
        '#default_value' => $display_builder,
      ]
    };

I will do the change
