Bowen Wang 877a9af2d1 rpmsg_virtio/rptun: support fallback cpuname when VIRTIO_RPMSG_F_CPUNAME not set

When the VIRTIO_RPMSG_F_CPUNAME feature is not negotiated, the driver
previously would crash due to DEBUGASSERT. This commit adds support
for a fallback mechanism:

1. Add rpmsg_virtio_probe_cpuname() API that accepts an optional cpuname
   parameter to be used when VIRTIO_RPMSG_F_CPUNAME is not available.

2. Modify rptun driver to pass the cpuname from rptun device config
   to rpmsg_virtio_probe_cpuname().

3. Refactor rptun device register/unregister to prioritize RPMSG device
   handling before other virtio device types.

This ensures the system works correctly in scenarios where the remote
side does not support the VIRTIO_RPMSG_F_CPUNAME feature.
