Update Tpm12.h and Tpm20.h and not use c++ reserved keywords
operator and xor in C structures to support use of these
include files when building with a C++ compiler.
This patch temporarily introduces an anonymous union to add
Operator and Xor fields to support migration from the current
field names to the new field names.
Warning 4201 is disabled for VS20xx tool chains is a temporary
change to allow the use of anonymous unions.
