Add a security manual for yocto walnascar.

The new manual is restructured to start with a step by step guide. It separates the build instructions and configuration from the security concepts.

Activating the eMMC boot partitions manually is not necessary because
partup takes care of that during provisioning.

Add a chapter on SSH certificate creation. SSH certificates are used to
access the device starting in walnascar.

Loading overlays.txt is disabled in securiPHY so it can not be used to
specify which overlays should be used.

Move the key generation script to the older manuals. It will be re-added
in a new chapter for new manuals. This separates security knowledge from
the concrete steps.

Move no longer relevant content to the manuals where it is still used.

Add the boot script as a new step in the secure boot chain between
bootloader and kernel fitImage. It is used in yocto walnascar and newer.

Replace the secure boot chain graphic to include the boot script as a
separate step.

Replace the head security manual with a walnascar security manual.
The manual is now structured as a step by step guide. It separates the
build instructions and configuration from the security concepts.
