BaseTools: Add support for version 3 of FMP Image Header structure 

Add support for the ImageCapsuleSupport field, introduced in version 3
of the EFI_FIRMWARE_MANAGEMENT_CAPSULE_IMAGE_HEADER structure. This
structure member is used to indicate if the corresponding payload has
support for authentication and dependency.
