WOO-856 ECom1 Dependency Cleanup

* Generic will no longer be called.
* Base64 encode/decode will be moved to ecom2.
* WordPress utility for fetching plugin specific requests will be moved to internal functions for now.
* Strings::isAssoc is now using ArrayValidator from ecom2.
* getAddress widget is temporarily fixed: Removed generic-fetchtemplate, and instead using ecom2-widget-fetcher with some global legacy-vars.
* Order data metaboxes is entirely disabled, while waiting for ecom2-templates.
* Removed WPUtils camel/snake-case handler.
* Setting frontend variable "environment" based on ecom2 instead. As we've reset the plugin, we switch over from ecom1 0/1 (prod/test) to the new set with "prod" and "test".
