Rework on A20_SDK images

I will rework the actual images to support also musl as an image. The plan is to remove the full images and make the base image to a glibc image. Then add a new musl based image. In the end i will support 2 different libc.

Convert images (from to)

Full Image -> remove

Base Image -> glibc

The new Image -> musl

The change will happen during the next weeks. So with A20_SDK_V2.9.4 the conversion will start.

Cheers
