  37   Check input P7Data is a wrapped ContentInfo structure or not. If not construct
  38   a new structure to wrap P7Data.
  39
  40   Caution: This function may receive untrusted input.
  41   UEFI Authenticated Variable is external input, so this function will do basic
  42   check for PKCS#7 data structure.
  43
  44   @param[in]  P7Data       Pointer to the PKCS#7 message to verify.
  45   @param[in]  P7Length     Length of the PKCS#7 message in bytes.
  46   @param[out] WrapFlag     If TRUE P7Data is a ContentInfo structure, otherwise
  47                            return FALSE.
  48   @param[out] WrapData     If return status of this function is TRUE:
  49                            1) when WrapFlag is TRUE, pointer to P7Data.
  50                            2) when WrapFlag is FALSE, pointer to a new ContentInfo
  51                            structure. It's caller's responsibility to free this
  52                            buffer.
  53   @param[out] WrapDataSize Length of ContentInfo structure in bytes.
  54
  55   @retval     TRUE         The operation is finished successfully.
  56   @retval     FALSE        The operation is failed due to lack of resources.
