Add priority field to rpmsg_endpoint structure to support
message prioritization. This allows different endpoints to
have different priority levels for scheduling purposes.
Changes:
- Define priority constants (MIN=0, DEFAULT=127, MAX=255)
- Add RPMSG_PRIO_RT alias for real-time priority
- Add priority field to struct rpmsg_endpoint
- Initialize priority to default value in rpmsg_register_endpoint()

To improve the share memory buffer utilization
1. Support release the rx buffer early, the ept->cb should return
RPMSG_SUCCESS_BUFFER_RETURNED to tell the rpmsg virtio the
rx buffer has been released;
2. Modifty name service callback to release the rx name service
message early;

1. call virtqueue_notification() only when buffer exist to avoid unnecessary
calls to virtqueue callback.
2. call virtqueue_notification() only when vq != NULL, because
rproc_virtio_notified() may be called when the virtqueues is not created:
virtqueue created in the virtio/vhost driver but the virtio devices
has been added to the remoteproc virtio devices list after the remoteproc
transport layer create the virtio devices.

So rpmsg virtio can alloc share memory from the virtio transport
layer and can work with various transport layer.

1. add cpuname config for the rpmsg virtio devices, so the rpmsg virtio
driver can get the local and remote cpuname from the virtio config
space, and we can distinguish the differnt channel when there are
two rpmsg virtio devices in the same resource table;
2. optimize the remoteproc virtio transport layer to make it can
work with all the virtio devices instead only work with rpmsg virtio
devices;

To avoid the crash when lock are acquired twice, one case is in the
destory process:
we hold the rpdev->lock to iterate the rpdev->endpoints to destory all
the endpoints, but rpmsg_destroy_ept() may send the name service message,
and need acquire the rpdev->lock again to lead crash.

Summary:
1. use nuttx/atomic.h instead of stdatomic
2. remove CONFIG_HAVE_ATOMIC,because we now support atomic on all platforms
Signed-off-by: chenrun1 <chenrun1@xiaomi.com>
When we use libmetal with other headers using stdatomic.h, we'll get
symbol conflict if we don't enable HAVE_STDATOMIC_H in libmetal. The
best solution might be using cmake to detect headers automatically, but
we can't. Fortunately we have CONFIG_HAVE_ATOMICS macro now, which can
replace HAVE_STDATOMIC_H when we're not using cmake.
Note: 2-Steps to use CONFIG_HAVE_ATOMICS
1. Include compiler.h for CONFIG_HAVE_ATOMICS definition
2. Check CONFIG_HAVE_ATOMICS instead of HAVE_STDATOMIC_H

1. Update all CMakeLists.txt to adapt to new layout
2. Fix cmake build break
3. Update all new file license
4. Fully compatible with current compilation environment(use configure.sh or cmake as you choose)
------------------
How to test
From within nuttx/. Configure:
cmake -B build -DBOARD_CONFIG=sim/nsh -GNinja
cmake -B build -DBOARD_CONFIG=sim:nsh -GNinja
cmake -B build -DBOARD_CONFIG=sabre-6quad/smp -GNinja
cmake -B build -DBOARD_CONFIG=lm3s6965-ek/qemu-flat -GNinja
(or full path in custom board) :
cmake -B build -DBOARD_CONFIG=$PWD/boards/sim/sim/sim/configs/nsh -GNinja
This uses ninja generator (install with sudo apt install ninja-build). To build:
$ cmake --build build
menuconfig:
$ cmake --build build -t menuconfig
--------------------------
2. cmake/build: reformat the cmake style by cmake-format
https://github.com/cheshirekow/cmake_format
$ pip install cmakelang
$ for i in `find -name CMakeLists.txt`;do cmake-format $i -o $i;done
$ for i in `find -name *\.cmake`;do cmake-format $i -o $i;done
