For historic reasons, ArmVExpress.dsc.inc defaulted to the ArmVExpress MMIO-based implementation of *Efi*ResetSystemLib - invoked via EmbeddedPkg/ResetRuntimeDxe. Since the majority of our platforms are now 64-bit and PSCI-based, flip this logic to default to the ArmPkg ArmSmcPsciResetSystemLib implementation of ResetSystemLib - with ARM-targets retaining the old behaviour.
At the same time update FVP and Juno targets to use the new generic ResetSystemRuntimeDxe.

OK, so you are intentionally keeping the 32-bit platforms on the reset runtime from EmbeddedPkg, and intend to address that later?
Correct. Doing that at the same time felt ... messy.
