Revert "ArmVirtPkg: Remove QemuRamfbDxe display device driver (RHEL only)"
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2087220
Display is not running using rhel9 machine type with edk2 and ramfb enabled due to missing ramfb driver. We removed this driver in downstream edk2.
Re-adding it again as we are supporting it in rhel9.
