Interface: Add 'tz' in file name for entry of TrustZone arch

File tfm_psa_ns_api.c contains unified entries for TrustZone
architectures. Compared with the entry file name for multi core
(tfm_multi_core_psa_ns_api.c), it is confusing for the TZ one being
named like a common file. So rename it to tfm_tz_psa_ns_api.c to make
its purpose easy to understand.
