Add secure storage service
Implements secure storage service client and provider. The client is
compatible with PSA Internal Trusted Storage API. There are two provider
versions implemented:
* mock_store is a dummy storage for testing purposes,
* secure_flash_store is a RAM based proof-of-concept storage solution
based on the ITS implementation in Trusted Firmware-M.
