Subject: [PATCH 1/4] tpm2: Add TPM2 types, structures, and command constants

Add new TPM2 types and structures as the preparation to support
authorized policy.

* New types:
  TPM_ALG_ECDAA, TPM_ALG_ECDSA, TPM_ALG_ECSCHNORR, TPM_ALG_RSASSA,
  TPM_ALG_RSAPSS, TPM_ALG_SM2, and TPMI_ALG_SIG_SCHEME

* New structures:
  TPMS_EMPTY, TPMS_SIGNATURE_RSA, TPMS_SIGNATURE_ECC,
  TPMS_SIGNATURE_ECDSA, TPMS_SIGNATURE_ECDAA, TPMS_SIGNATURE_SM2,
  TPMS_SIGNATURE_ECSCHNORR, TPMU_SIGNATURE, and TPMT_TK_VERIFIED

* New command constants:
  TPM_CC_LoadExternal, TPM_CC_HashSequenceStart, TPM_CC_SequenceUpdate,
  TPM_CC_SequenceComplete, TPM_CC_Hash, TPM_CC_VerifySignature,
  TPM_CC_PolicyAuthorize
