For the LIN protocol, the error frame ID can be 0. This change is to ensure that all LIN error frames can pass the filter.

Add aligned_data(STACK_ALIGNMENT) attribute to g_irq_work_stack buffer declaration
in irq_attach_wqueue.c. Ensures stack memory is properly aligned to architecture
requirements, preventing unaligned stack addresses that could cause data access
faults or performance degradation on strict alignment architectures.

Move nxsched_switch_context() call after setting TSTATE_TASK_INACTIVE to ensure

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.

Because virtio device do not need manager the share memory heap
for now.
But later we will make the virtio device be able to manager a
standalone heap, so let this logic can be easily to extend.

If there are multiple virtio devices in rsc, it must wait for the previous
device to be created before creating the next one. In this case, if the
driver configuration of a device is not be set Y, the subsequent virtio
devices cannot be created.

Because rptun do not want part of the share memory is used by the

1. Save the share memory;
2. Some platfrom can't use atomic operation at the share memory,
and struct mm_heap_s contains a mutex.

Support enable/disable the kasan when initialize the heap.
This requirement is from rptun, because rptun use share memory init
the heap and share memory is precious, so we need disable the kasan
feature for rptun's heap to save the share memory.
