Enhance RelocateCapsuleToRam() to skip creation of the Capsule on Disk
file name capsule if PcdSupportUpdateCapsuleReset feature is not enabled.
This avoids an EFI_UNSUPPORTED return status from UpdateCapsule() when the
file name capsule is encountered and PcdSupportUpdateCapsuleReset is FALSE.

Hi Liming,
BuildSg is supposed to mean 'Build Scatter-Gather'. Maybe 'BuildGather' would be a better goto label since it matches the comment and the function?
Let me know.
Thanks,
