New in v2
==========
Changes from 2 patches to 3 patches to support bisect. This
temporarily uses an anonymous union to allow use of both field
name styles. It also allows downstream usage of these fields
to sync with the first 2 patches, update their field names,
and then sync with last patch.
PR: https://github.com/tianocore/edk2/pull/4436
===========
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.
Update SecurityPkg Tpm2CommandLib to use updated field names.
* Change operator -> Operator
* Change xor -> Xor
NOTE: This is a non-backwards compatible change to Tpm12.h
and Tmp20.h. And consumers of these include files that access
the "operator" or "xor" fields must be updated.

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.

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 removes the temporary use of anonymous unions and
warning 4201 disable for VS20xx tool chains to complete the
following field name changes:
* operator -> Operator
* xor -> Xor
NOTE: This is a non-backwards compatible change to Tpm12.h
and Tmp20.h. And consumers of these include files that access
the "operator" or "xor" fields must be updated.

Hi Mike
Do you think if we can enhance CI to catch such keyword?
I don't mean to need it in this patch, but something we could consider later.
Thank you

SmbiosView will print:
Slot Id: undefined Slot Id
Updating this check to Gen6andBeyond which fixes the problem:
Slot Id: the value present in the Slot Number field of the PCI Interrupt

Do you know if this works cleanly for the other toolchains? i.e
supported GCCs and CLANGs?
I don't *think* there's a warning for anonymous unions beyond passing
-pedantic + -std=c<something>, but it'd be good to know.
If so, we may need a pragma for this.

All in all, this looks ok to me. Although I have to say, I'm not a
huge fan of the naming style inconsistency introduced here (i.e Xor vs
hmac).
What if we made all the struct members MixedCase? Or what if we did
something like calling them xor_ and operator_?

The more we change, the greater the potential impact to downstream use of
these structures. I prefer to do the smallest possible change to address
the c++ reserved keyword name collisions in this patch series.
I do not have strong opinion between 'xor_' vs 'Xor'. These files are
based on the TCG TPM Specifications that typically start field names with
lower case and camel case after that for multi-word field names.

Hi Pedro,
It appears other projects have run into this same issue with the
TPM specifications and have changed the field names by appending '_'.
