When TrustFence is enabled, a PKI tree is generated.
In the case of NXP platforms, the PKI contains public certificates
from which the public key needs to be extracted using an openssl
command.
In the case of STM platforms, the PKI contains directly the
public key.
In all cases, we need the public key to be installed in the
rootfs /etc/ssl/certs/ folder, so that it can be used by
swupdate to authenticate signed SWU packages.
Up to now, this was being done on the dualboot recipe, but the
installation of the public key should really be only dependant
on the fact of TF being enabled.
This commit:
- Removes the generation of the public key from dualboot.bb.
- Generates a patch to extract the public key from the certificate
as part of the PKI tree generation (on NXP platforms).
- Installs the public key during a post install function after
the final rootfs has been created.
- For NXP platforms, extracts the public key using openssl if
it does not exist (for backwards compatibility).

The root file system requires the public key to authenticate SWU files.
For NXP platforms, the public key is extracted from the certificate.
For STM platforms, simply copy the public key over to the rootfs.

Several recipes depend on the PKI creation.
Create a small recipe to just run this function which
is moved from the trustfence.bbclass.

dualboot and recovery recipes may require to use the keys so they must
depend on the recipe that installs the script that generates them.

The stand-alone signing script 'trustfence-sign-artifact.sh' checks
if a valid PKI tree exists (by checking the existance of four SRK
files) and if they don't, it calls trustfence-gen-pki.sh (which is
a wrapper over different generators (for HAB or AHAB) to create one.
Recipes such as 'dualboot' or 'recovery-initramfs' may need to call
openssl functions over the PKI tree. These recipes do not currently
generate the PKI tree; they expect it to be already in place.
This might not be the case if the trustfence-sign-artifact.sh script
has not been called yet.
Originally, a fake dependency on virtual/kernel recipe was made to
force it, but it doesn't quite work since the calling only happens
on deploy() while regular DEPENDS doesn't wait for this task.
If the PKI does not exist, a recipe that requires the PKI tree will
fail.
The solution is to create a function on the trustfence.bbclass that
allows any recipe to check for the existance of a PKI tree and
generate it if it doesn't exist. This is repeated inside the
trustfence-sign-artifact.sh, but it needs to be in both places
because this script must work stand-alone.
The generation of the PKI tree takes some seconds so this commit
adds a lock dir to prevent race conditions when called from
different recipes.
It also removes the fake dependency on virtual/kernel and adds a
dependency on trustfence-cst-native (which is the recipe that
provides the PKI generation tool).

https://onedigi.atlassian.net/browse/DEL-8430
(cherry picked from commit 6a8bf7afff)
Several fixes to the runtime dependences:
* Use new override syntax with ':'
* There is not "dualboot-init" package only "dualboot"
* Delete dependence on trustfence-tool
While on it, define do_configure and do_compile as noexec, because those
tasks do not need to execute, and remove the wrong PACKAGE_ARCH entry
(as this package is arch/machine agnostic)

According to the Yocto reference manual, we need to specify the package name
override to indicate the package to which the value applies.

Use the same name for both firmware update mechanism.
Add a dependency to only add recovery-utils used by the
non dual-boot firmware update system.
Adding this only one binary/script called update-firmware will
be added.

- create dualboot.bbclass that
- sets DUALBOOT_ENABLED variable
- defines partition names and function for changing the sw-description
for swupdate
- move files from layer into meta-digi
