Subject: [PATCH v2] edk2Platforms-Silicon:Add VAB FIT record types support in FitGen.c



REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4086



This commit adds support for new FIT record type for Vendor Authorized Boot (VAB) security technology(FIT spec revision 1.4).

VAB defines 3 new following types

Vendor Authorized Boot Provisioning Table (Type 0x1A) Vendor Authorized Boot Image Manifest (Type 0x1B) Vendor Authorized Boot Key Manifest (Type 0x1C) The code has been updated to align these binaries on 64 byte boundary and not to overlap with other regions, similar to Key manifest, Boot Policy manifest and other optional types.



Also added macros to define FIT spec Major and Minor version numbers and print the same instead of hardcoded string.
