This commit added ifdef macro to sigwork_s. When CONFIG_SIG_EVTHREAD is
not defined, the struct sigwork_s will be empty struct, which is helpful
to reduce bss size.

The aforementioned functions can/will fail if the C compiler decides
to use the stack for the incoming entrypt/etc. parameters.
Fix this issue by converting the jump to user part into pure assembly,
ensuring the stack is NOT used for the parameters.
When its remote core publishes a message, all subscribed cores will receive the message,
but the local core "stublist" does not update the user's "generation" and "bufferpos" parameters.

The original code made the incorrect assumption that the amount of
translation levels is 3, but this is incorrect. The amount of levels is 4
and the amount of levels that are utilized / in use is set dynamically
from the amount of VA bits in use.
The VMSAv8-64 translation system has 4 page table levels in total, ranging
from 0-3. The address environment code assumes only 3 levels, from 1-3 but
this is wrong; the amount of levels _utilized_ depends on the configured
VA size CONFIG_ARM64_VA_BITS. With <= 39 bits 3 levels is enough, while
if the va range is larger, the 4th translation table level is taken into
use dynamically by shifting the base translation table level.
From arm64_mmu.c, where va_bits is the amount of va bits used in address
translations:
(va_bits <= 21) - base level 3
(22 <= va_bits <= 30) - base level 2
(31 <= va_bits <= 39) - base level 1
(40 <= va_bits <= 48) - base level 0
The base level is what is configured as the page directory root. This also
affects the performance of address translations i.e. if the VA range is
smaller, address translations are also faster as the page table walk is
shorter.
This defconfig is an example of the recorded stack and it became
faulty recently after the implementation of the `up_current_regs`
functions. The `noinstrument_function` directive must be used for
preventing it from being looped when instrumentation is enabled.
Also, this commit places `sched/instrument/stack_record.c` in IRAM.
with other functionalities removed.
reason:
by doing this we can reduce context switch time,
When we exit from an interrupt handler, we directly use tcb->xcp.regs

After the ap core subscribes to the 25hz batch 120ms data of the sensor core, it switches
to the cp core and subscribes to the 50hz batch 120ms sensor core data. At this time,
the data subscribed by the AP will be abnormally lost (12.5hz). Mainly because ap
subscribes to sensor core data earlier than cp. The subscription of cp will be broadcast
to the ap core at the same time, and the corresponding "path" already exists
under "/dev/uorb" of ap. Thus the ap will create a "stub".
There are some restrictions on the creation of "stub" to avoid this situation.
