After addrenv_switch(), the current running task (this_task) may change due to
deferred work execution. Update all architecture interrupt, syscall, and exit
handlers to re-fetch tcb = this_task() after addrenv_switch(). Ensures scheduler
and context operations use the correct TCB, preventing context corruption and
exceptions across SMP and memory-protected builds.

In SMP mode, running tasks are in g_assignedtasks[cpu], not the
ready-to-run list, so tcb->flink is NULL. When a round-robin timeslice
expires, checking tcb->flink fails to find the next task.
Fix by calling nxsched_switch_running() directly in SMP mode when the
timeslice expires, which properly finds the next eligible task from the
ready-to-run list.

Move addrenv_join() call after group_initialize() in nxtask_setup_fork() to fix
null pointer dereference. addrenv_join() accesses child->group which is
initialized by group_initialize(), so the operations must be sequenced
correctly. Reorder initialization to ensure child task group is set up before
address environment join operations.

The rwcnt (read word count) field in ctucanfd_frame_fmt_s was previously
limited to 4 bits, allowing a maximum value of 15. This is insufficient
to correctly represent the frame size (excluding the FRAME_FORMAT word)
for larger CAN FD frames as required by the CTU CAN FD hardware.
Increase the rwcnt bitfield width to support a larger range and adjust
the structure layout so that ctucanfd_frame_fmt_s has a size that is a
multiple of 4 bytes, as required by the hardware interface.
This change improves correctness and robustness when handling larger
CAN FD frames without affecting existing users.

Add new CONFIG_NCPUS configuration option to support both SMP and AMP modes.

We have added a defconfig configuration to set the page size of the flash.
According to the CFI protocol, the flash supports a single write operation
with a data volume ranging from byte size up to the maximum number of bytes.
However, the MTD device structure requires defining a page size, which serves
as the minimum write unit of the flash. Hence, this configuration is introduced.
Any page size within the range of 1 to the maximum number of bytes is considered
valid.
