debug: fail to show active cpu stacks [1/1]

PD#SWPL-4718

Problem:
The task stack address is not saved to irq_stack_ptr-0x08,
so when switching from irq stack to task stack, we can not
obtain the right task stack address

Solution:
save task stack address to irq_stack_ptr-0x08

Verify:
Locally on Ampere
