Config: Share one project config file among arch tests

There is only little difference among project config files for different
arch tests. To keep code clean, it is good enough to share a single
project config file among arch test suites.

Library tfm_config is set before loading PSA configs, to make sure that
arch test related compile definitions can be correctly added to tfm_config.
