Add psa_trusted_storage_linux persistent storage support for v1.0.0 APIs

Browse Source 
The following provides more information on this PR:
- PSA stands for Platform Security Architecture.
- Add support for use of psa_trusted_storage_api internal_trusted_storage.h v1.0.0
  as the interface to the psa_trusted_storage_linux backend (i.e. for persistent
  storage when MBEDTLS_PSA_ITS_FILE_C is not defined). This requires changes
  to psa_crypto_its.h and psa_crypto_storage.c to migrate to the new API.
