Add ingredient editor components

[tvdeyen]

What is this pull request for?

Instead of rendering partials and having logic splattered
across helpers and a decorator that has methods for all
ingredients, we now have self contained component classes
for each individual ingredient.

Notable changes

Deprecates the Alchemy::Admin::IngredientsHelper and the Alchemy::IngredientEditor decorator.

Upgrade notes

Custom ingredient editor partials are deprecated - Apps with custom app/views/alchemy/ingredients/_*_editor.html.erb partials will see deprecation warnings. Migrate to ViewComponent-based editors by creating a class inheriting from Alchemy::Ingredients::BaseEditor.

Example migration:

# app/components/alchemy/ingredients/color_editor.rb
module Alchemy
  module Ingredients
    class ColorEditor < BaseEditor
      def input_field(form)
        # your custom input
      end
    end
  end
end
