[TASK] Clean up drawing configuration for Fluid-based page module

PageLayoutView now builds a "Configuration" model for both variants
PageLayoutView is not set up via the DrawingConfiguration object,
which is now based on a factory method.

PageLayoutController now injects all RequireJS modules in one place,
and not in fluid anymore.

Minor bugs regarding "getLanguageColumns" are fixed.

The main "pageLayoutConfiguration" is now injected and used where it does not
differ from the backend module configuration.
