add-in remaining VideoCore VC4 devices in video group

vchiq driver creates several devices:
/dev/vchiq
/dev/vcio
/dev/vcsm-cma
/dev/vc-mem

Let's set them in video group so that users from that group can use them with video/graphics related apps.

This translates 10-local-rpi.rules found in libraspberrypi0 PiOS package
KERNEL=="vchiq", GROUP="video", MODE="0660"
SUBSYSTEM=="vc-sm", GROUP="video", MODE="0660"
KERNEL=="vcio", GROUP="video", MODE="0660"
