change version to newest one - 'head' instead of revision number, found that when trying to compile v0.3.5 to get register data dump, as in discussion on Matrix,
last change in radio_tool master is from 5 Oct 2023, more over year old so it should be pretty stable
Add west manifest contributed by edgetriggered to allow automated
cloning of the correst Zephyr revision.
Now codec2 dependency is enabled also for T-TWR build, enabling to build
it from scratch without first building a Miosix target.
Enabled non-cross build to use codec2 compiled sources.
Begin implementing PMU, now successfully read and write registers, need
to implement button functionality, battery voltage readout, charge
detection etc.
TG-553
Now radio tool is checked out, compiled and used as a submodule,
removing the need of installing it as an external dependency and
ensuring consistency in the tool version.
