make possible enable pool, but disabled in system heap.
also compatible for further extra heap use/not use pool.
Now use MM_HEAP_MEMPOOL_THRESHOLD -1 to indicate pool disabled.

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.
test:
We can use qemu for testing.

If the CAN stack receiving packets fast, but the application layer reading packets slow. Then `conn->readahead` will continue to grow, leading to memory leaks. Finally CAN stack potentially starve out all IOB buffers. To prevent memory leaks, users can restrict can socket buffer length.

pointer comparison is unsigned, when returning -errno will be converted
to a large positive number, can not enter the error handling branch,
therefore, the error code is returned directly and the sem is returned
through the parameters.

After change, when CONFIG_PM_NDOMAINS > 1,
the pm_register will not able to get notificaion
from not PM_IDLE_DOMAIN.
Should use pm_domain_register as a replacement.
Isolate domains from global callbacks can decrease
not necessary execution, and reduce the
lock instruction requirements.

MCP794XX supports digital trimming that periodically adds or subtracts
clock cycles, resulting in small adjustments in the internal timing.
This way inaccuracies of clock source can be compensated.
This commit adds option to set the trimming register for MCP794XX.

The definition of nxsched_process_cpuload_ticks uses clock_t, which is
portable across uint32_t and uint64_t timers, and works if CONFIG_SYSTEM_TIME64 is
defined.
only when first time change state can hold WFI for enough time thresh,
allow second time goto target state,
suitable for the case when wakeup from sleep too slow, etc.

Some drivers may set too big quota by accident and consume all of our
buffers, so we add a check when registering devices.
