* Theme extensions
Adds the ability to choose the themeing strategy: Extend one of the existing themes (light or dark) or go fully custom. The latter was the only option up to now, which isn't ideal:
- One had to provide a full-blown theme file overriding all variables
- Tedious, error prone and hard to maintain, because one has to keep track of updates
This PR makes it so that one can choose light or dark as base theme and do modifications on top.
Benefit: You can specify a limited set of variables and might get away with 5-20 lines of CSS.
* Ensure custom theme is present
* Update checkout test
* Move TagHelpers to Abstractions
Makes them available for use in plugins. Also cleans up the tag helper references in the view code: As we have it in the root view imports, the individual directives in the views are superfluous.
* Move CurrenciesSuggestionsTagHelper back
To get rid of the Rating dependency in Abstractions.
* Remove Bootstrap/Creative CSS file customizability
Customizations should be done using themes

They are still available in the design system repo and should be added as custom theme CSS file
