Torsten Rasmussen 1cccc8a8fe cmake: increase minimal required version to 3.20.0
Move to CMake 3.20.0.

At the Toolchain WG it was decided to move to CMake 3.20.0.

The main reason for increasing CMake version is better toolchain
support.

Better toolchain support is added in the following CMake versions:
- armclang, CMake 3.15
- Intel oneAPI, CMake 3.20
- IAR, CMake 3.15 and 3.20
