Move stack alignment and kernel stack macros from architecture-specific internal
headers to public include/nuttx/irq.h. Consolidates duplicate definitions across
17 architecture families, reducing code duplication while enabling common code
to access these core alignment utilities without architecture dependencies.

When _LIBCPP_HAS_NO_CONTENTION_TABLE is defined, libcxx will not
allocate the contention table used for semaphore implementation,
which can save significant RAM on memory-constrained embedded systems.
This optimization is particularly useful for NuttX targets where
every byte of RAM matters.

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.
