Rename arm64_addrenv.c to arm64_addrenv_mmu.c to separate MMU-specific logic.
Add new arm64_addrenv_mpu.c with stub implementations of address environment
functions for MPU-based systems. Enable address environment support in FVP ARMv8-R
Kconfig to support kernel stacks in protected mode. Conditionally build MPU or
MMU address environment code based on CONFIG_ARCH_USE_MMU/CONFIG_ARCH_USE_MPU.

The limit register contains the enable/disable bit for the MPU region,
so it must be written first before writing the base register to ensure
proper region disable operation.

In multi-core scenarios, a problem occurs: the target thread receives SIGCONT but does not execute them.
Further analysis reveals that in the sig_dispatch function, the target thread is placed in the readytorun queue only if the SIGCONT signal is sent and the target thread is in the TSTATE_TASK_STOPPED state. However, if the following conditions occur:
CPU0 CPU1
dispatch SIGSTOP
dispatch SIGCONT(check state)
sched_suspend(set task_state = TSTATE_TASK_STOPPED)
This causes the target thread on CPU 1 to receive SIGCONT but not be placed in the readytorun queue, remaining in the stopped state.
Therefore, A flag is needed to indicate whether the SIGCONT action has been executed. At the same time, the critical section protection range of nxsig_stop_task needs to be expanded to prevent another thread from executing the SIGCONT logic during the execution of this function.

Previously the ioctl-based configuration was not encoded properly.
It lacked the three command bits selecting the "set volatile
configuration" mode.
Thus, configuration the reference, power-down or gain resulted in no
change.
Now the configuration is properly applied.
The DAC value to be send is now combined with the proper command prefix
bits, too.
But this operation was already working, since the command prefix is zero.
