ArmVirtPkg/ArmVirtQemu: Add RngDxe driver 

Add the RngDxe driver to the build, backed by either RNDR or TRNG, one
of which is expected to be available in most cases:
- RNDR is implemented by the 'max' CPU that QEMU implements in TCG mode
- TRNG is implemented by the KVM hypervisor, which backs QEMU's 'host'
  CPU

Other TCG modes (e.g., the 'cortex-a*' CPUs) implement neither, which
should prevent the RngDxe driver from dispatching entirely, resulting
in the same situation as before.
