Re-implement features

[PhilippvK]

This issue should should list all the features we want to support until the release of the project.

---

First I would like to shortly explain the features types which are denoted after each entry on the list:

• Setup Feature: For features which required installing specific dependencies beforehand. Affecst the mlonmcu setup command.
• Frontend Feature: Frontend related features are used in the LOAD stage of a run. (i.e. packed)
• Framework/Backend Feature: Features specific to a backend or framework (i.e. unpacked_api). Affects the BUILD stage of a run.
• Target Feature: Target specific features (i.e. etissdbg). Affects the COMPILEand RUN stage
• Compile Feature: MLIF/CMake related features (i.e. debug). Affects the COMPILE stage
