[nrf fromlist] dts: nordic: nrf54h20_enga: add PPR VEVIF nodes

Add a new nodes for PPR's VEVIF. In app cores, VEVIF registers are part of the VPR peripheral, so it is exposed as a child node (since it requires its own properties, eg #mbox-cells). In VPR, it's a CPU child since it's not a memory-mapped peripheral, but used with CSRs.
