ArmVirtPkg/PrePi: remove bogus primary core check
QEMU and KVM based ARM/AARCH64 virtual machines only enter UEFI on a single core, so ArmPlatformIsPrimaryCore() always returns true. And even if it didn't, our code does absolutely nothing meaningful based on its return value, so don't bother calling it, and remove another frivolous dependency on ArmPlatformLib.
