reason:
In the kernel, we are planning to remove all occurrences of up_cpu_pause as one of the steps to
simplify the implementation of critical sections. The goal is to enable spin_lock_irqsave to encapsulate critical sections,
thereby facilitating the replacement of critical sections(big lock) with smaller spin_lock_irqsave(small lock)

Revert "Parallelize depend file generation"
This reverts commit d5b6ec450f.
parallel depend ddc does not significantly speed up compilation,
intermediately generated .ddc files can cause problems if compilation is interrupted unexpectedly

reason:
1 On different architectures, we can utilize more optimized strategies
to implement up_current_regs/up_set_current_regs.
eg. use interrupt registersor percpu registers.

Newly added logging in `sched/task_exit.c` obsoletes the existing
ones in `arch/up_exit()`, thus remove the latter to reduce duplications.

The `xxx_ipv6multicast` function in each driver is not adapted to
multiple IPv6 addresses yet, and they're redundant, so try to take them
into common code.
Change:
1. Add MAC `g_ipv6_ethallnodes` and `g_ipv6_ethallrouters` in
`icmpv6_devinit` and call them in `netdev_register`
2. Add multicast MAC for Neighbor Solicitation when adding any IPv6
address, and remove them when IPv6 address is removed
3. Select `NET_MCASTGROUP` when `NET_ICMPv6` because now we need
`d_addmac` when we have ICMPv6
Note:
We want modules outside net stack to call functions like
`netdev_ipv6_add` and never touch the related MAC address, so these MAC
functions are added as internal functions to `net/netdev/netdev.h`

When supporting high-priority interrupts, updating the
g_running_tasks within a high-priority interrupt may be
cause problems. The g_running_tasks should only be updated
when it is determined that a task context switch has occurred.

to avoid getting the value of fp from up_getsp and causing
incomplete stack printing.
2. Determine which stack the value belongs to based on the value
of SP to avoid false reports of stack overflow

status. In most cases, we know the task status, so we can directly
add the task from the specified task list to reduce time consuming.
