debug.h is a NuttX-specific, non-POSIX header. Placing it in the
top-level include/ directory creates naming conflicts with external
projects that define their own debug.h.
This commit moves the canonical header to include/nuttx/debug.h,
following the NuttX convention for non-POSIX/non-standard headers,
and updates all in-tree references.
A backward-compatibility shim is left at include/debug.h that
emits a deprecation #warning and re-includes <nuttx/debug.h>,
allowing out-of-tree code to continue building while migrating.

Convert VHOST_DEFERED_PROBE_PERIOD from a raw value to use MSEC2TICK()
macro, ensuring the delay is correctly converted from milliseconds to
system ticks regardless of the configured tick rate.

Add vhost_get_vq_buffers() API to retrieve all chained buffers from a
virtqueue in one call. This simplifies handling of scatter-gather I/O
where data spans multiple descriptors.
The function populates an array of virtqueue_buf structures with buffer
pointers and lengths, returning the descriptor head index on success.

So the driver can get the driver pointer by vdev/hdev->priv,
and later vdev/hdev->priv can be used to store other data such as the
virtio/vhost drivers' private data.

vhost-rng is a simple virtio device implementation, it receives
the buffer receviced from the virtio-rng driver and fill the random
number to this buffer and return to virtio-rng.

virtio is a framework to implement the virtio drivers
vhost (Virtual Host) is a framework to implement the virtio devices
With the virtio and vhost framework, we can use the virtio drivers
and vhost drivers to implement the cross-core communication.
