radv: cleanup physical device variables naming and use the base object more often
This MR is a cleanup and it does the following things:
- rename physical_device variables to pdev instead of phys_device, phys_dev, pdevice, physical_device etc (shorter and more consistent)
- rename radv_physical_device::rad_info to info (extra rad_ is unnecessary)
- use the base object more often instead of eg. cmd_buffer->device->physical_device etc (loosely based on NVK)
