Attest: Remove fetching claims info from shared memory

Currently, the security lifecycle, boot seed, and hardware version
info are searched in the shared memory first before calling the
platform hal API. Sharing this information via shared memory
is not the designed way anymore. The related code is a legacy.
This patch removes the legacy code.
