Move attestation related code to seperate compilation unit

Attestation related functions from KeymasterContext are never called by
AndroidKeymaster but rather by the code that imiplmenets attestation.
Therefore, this patch moves this interface from KeymasterContext to
AttestationRecordContext in attestation_record.h.

Also
- Move attestation key material to contexts/soft_attestation_certs for
  reuse by other contexts.
- Moved attestation related code from asymmetric_key to
  attestation_utils.
