According to the PCDs not used by modules or in conditional directives
sections of all the build reports for {AARCH64,ARM} x {Xen} x {DEBUG,NOOPT,RELEASE} x {feat-1} (6 builds in total), PcdOptionRomImageVerificationPolicy, PcdFixedMediaImageVerificationPolicy, and PcdRemovableMediaImageVerificationPolicy are not used in any of those builds. Restrict the settings to the ArmVirtQemu and ArmVirtQemuKernel platforms (preserving the -D SECURE_BOOT_ENABLE restriction in the process). ("feat-1" stands for "-D HTTP_BOOT_ENABLE -D NETWORK_IP6_ENABLE -D SECURE_BOOT_ENABLE -D TTY_TERMINAL", while "feat-0" stands for "".)
