Feature: #63729 - Introduce GruntJS

See Issue #63729

Description

In order to unify build processes in the backend we introduce GruntJS as a central taskrunner. It will provide a global config that takes over the responsibility for all build processes in the future starting with the less files of the backend skin.

The build files are located in the Build folder located in the root directory.
