sched：remove g_cpu_schedlock g_cpu_irqsetlock g_cpu_locksetlock

[hujun260]

Summary

we can use g_cpu_lockset to determine whether we are currently in the scheduling lock, and all accesses and modifications to g_cpu_lockset, g_cpu_irqlock, g_cpu_irqset are in the critical section, so we can directly operate on it.

Impact

Testing

test: We can use qemu for testing.
