feat(tc): provide target_locality info of AP FW components
The target_locality attribute is meant to specify that
a certain SW component is expected to run and thereby
send DPE commands from a given security domain. The DPE
service must be capable of determining the locality of
a client on his own. RSE determines the client's locality
based on the MHU channel used for communication.
If the expected locality (specified by the parent component)
is not matching with the determined locality by DPE
service then command fails.
The goal is to protect against spoofing when a
context_handle is stolen and used by a component
that should not have access.
