Update SmBios header file to conform with SMBIOS v3.3.0.
Ah, I note SMBIOS 3.3 has not yet been released - so this can not be
merged in edk2 master at this point. I did not realise this when I
requested you send the patch.
Please submit BZ https://bugzilla.tianocore.org/ for this update. This is a new feature.

However, you can carry this in your edk2-staging branch, and once the
specification gets released we can take it into edk2.

(After code review, a couple of minor comments below.)

The major update is to add definitions of SMBIOS Type 44h record.
