Because locate the command at the end the resource table is unfriendly

Add more common command for rptun and rpmsg_virtio frameworks,
also modify the rptun and rpmsg_virtio driver to use the common
commands.

Move the panic logic in common places, later we can move more logic to
the framework instead of having the drivers implement it repeatedly.

headrx is very convient to check weather current core miss interrupt
by comparing the headrx with the rx vring avail.idx for slave side or
rx vring used.idx for master side.
So move headrx out of the CONFIG_RPTUN_PM range.

Store the rx virtqueue idx to the local headrx index, and only
process the data when the rx virtqueue has data to avoid access
the ram in low power mode.

Add get_local_cpuname to the rpmsg framework ops to support communicate
with the same remote core with multi rpmsg transport.
Some rpmsg services will send local cpu name to remote core and then let
remote core to connect local core by using this cpu name, when there are
multi rpmsg channels with same remote core, the remote core may connect
to incorrect core, so use the error rpmsg channel.
For example, there are two rpmsg channels between ap and audio:
ap core audio core
[ap1] <-- rpmsg virtio1 --> [audio1]
[ap2] <-- rpmsg virtio2 --> [audio2]
When we want to use the rpmsg virtio1 to communicate, ap core may send
local cpuname "ap2" to audio, so the audio core use remote cpu "ap2" to
connect with ap, and resulting in the use of incorrect rpmsg channel.

In the previous patch, we moved rptun_panic and rptun_dump_all in rptun to rpmsg.
In order to ensure CI pass, this two API in rptun is not removed. So we remove rptun_panic and rptun_dump_all in this patch.
