Create a new script for the generation of PKI tree for STM platforms
and leave the trustfence-sign-artifact script exclusively for signing.
The new gen-pki script only requires the platform as an argument and the
path to where to save the tree (if it doesn't exist) in
CONFIG_SIGN_KEYS_PATH.
This commit also reverts commit 13c136dbc5 by getting rid of the
trustfence-genpki-native.bb recipe and moving back the PKI generation
functions into trustfence.bbclass. This recipe didn't quite guarantee
that the PKI was generated on time for the recipes that required the
keys to exist, anyway.
Instead, the PKI generation function must be called right after
do_compile() of recipe tf-a-stm32mp to be ready for do_deploy() where
the key is used.

This script can be called stand-alone or from DEY.
Syntax is :
trustfence-sign-artifact.sh -p <platform> [-t input-unsigned-image> <output-signed-image>]
If files are omitted, it at least generates random keys if they do not
exist.
