[Microwin] dedicated Function folder

[MyDrift-user]

Type of Change

• Refactoring

Description

• To make working on Microwin easier and as a preparation step for the Runspaces for Microwin PR this moves content related to microwin to its own folder "Microwin" in "functions".
• In addition to that the Microwin Helper is devided into one function per file, like most other functions at this point.
• I renamed the functions to apprehend them into runspaces (for other Draft PR) and to have a standardized naming scheme.

Testing

• done, works.

Impact

• better maintanance of Microwin
