Move the definitions of PSA core and builtin
source paths to pre_initialize_variables
where they are merged with the definition
of the configuration file paths.
Add the 3.6 case by the way as
pre_initialize_variables is planned to
be in the all.sh part that will land in
mbedtls-framework at some point.
