SST: Rename get_attributes APIs to get_info

This patch renames get_attributes functions to get_info, and updates
the SST code as follows:
- rename tfm_sst_attribs_t to tfm_sst_asset_info_t
- rename sst_asset_infoi_t to sst_asset_policy_t in
  sst_asset_management
- add sst_core_obj_info_t in sst_core
- update sst service APIs and code to accomodate it to the new types
  and type names
- update dependant tests to accomodate them to the new names
