hujun5 ed998c08c4 sched: change the SMP scheduling policy from synchronous to asynchronous
reason:
Currently, if we need to schedule a task to another CPU, we have to completely halt the other CPU,
manipulate the scheduling linked list, and then resume the operation of that CPU. This process is both time-consuming and unnecessary.

During this process, both the current CPU and the target CPU are inevitably subjected to busyloop.

The improved strategy is to simply send a cross-core interrupt to the target CPU.
The current CPU continues to run while the target CPU responds to the interrupt, eliminating the certainty of a busyloop occurring.
