Set minimum CMake version to 3.21
* Update documentation to list CMake 3.21 as the default version. This
brings the documentation in line with the cmake files, which already
use 3.21 as the minimum version.
* Downgrade the CMake version required by the IAR build from 3.22 to
3.21. This makes the CMake minimum version consistent across the
entire repository. (similar work is required for an example in
tf-m-extras).
