* [libcpu] support for ARCH_REMAP_KERNEL
These changes introduce support for the ARCH_REMAP_KERNEL configuration,
which isolates kernel space in high virtual address regions. This feature
is necessary to enhance memory protection and management by segregating
user and kernel spaces more effectively.
Changes:
- Updated conditional macros to check for ARCH_REMAP_KERNEL instead of
ARCH_KERNEL_IN_HIGH_VA in board initialization files to reflect the new
configuration option.
- Modified qemu-virt64-riscv Kconfig and SConstruct files to include and
utilize ARCH_REMAP_KERNEL.
- Created a new linker script `link_smart.lds` for smart linking in qemu-virt64-riscv.
- Updated rtconfig.py to use a more flexible execution path setup.
- Enhanced user address space definitions in `lwp_arch.h` to support the
new virtual address mappings.
- Adjusted kernel memory initialization and mapping logic in `c906/mmu.c`
and `virt64/mmu.c` to account for high virtual address regions.
- Added Kconfig option to enable ARCH_REMAP_KERNEL for RISCV64 architectures.
- Enhanced memory setup functions to support new mapping scheme, including
updates to early page table setup and address relocation logic.
These modifications ensure that the system can utilize high memory
addresses for the kernel, improving memory isolation and system stability.

This patch fixup the script execution capabilities on argv passing
and adds support for arguments larger than 4k.
According to POSIX, the script parameter is quiet different
from the current implementation. Especially on the way it inserts
the path of executables. At the end, when you execute a script
from `$PATH`, it always fails.
For the script, interpreter will be invoked with the following
arguments: `{interpreter [optional-arg] pathname arg...}`
where pathname is the pathname of the file specified as the first
argument of execve(), and arg... is the series of words pointed
to by the argv argument of execve(), starting at argv[1]. Note that
there is no way to get the argv[0] that was passed to the
execve() call.
The changes include:
- Separating argument, environment variable, and auxiliary vector
processing into a new lwp_args.c file.
- Fixing bugs in script argument processing and supporting arguments
larger than 4k.
- Updating lwp_execve to use the new argscopy function and removing
the old lwp_argscopy function.
- Making various modifications to lwp_load and elf_aux_fill to work
with the new argument processing.
- Removing unnecessary code related to dynamic loading and interpreter
scripts.

Correct `sched_setaffinity()` to use the thread IDs (TIDs) instead of
process IDs (PIDs). The previous implementation used PIDs, which
caused issues since affinity settings need to be applied at the
thread level.
As the manual documented, the signature is:
> int sched_setaffinity(pid_t pid, size_t cpusetsize,
> const cpu_set_t *mask);
Yes, it's tricky, the identification passing in is called **'PID'**.
But when we talk about 'pid' from GNU libc, it's the **'task-id'**,
aka, `thread->tid` known in kernel.
Changes were made by updating the function signatures and logic in
`lwp.h`, `lwp_pid.c`, and `lwp_syscall.c` to accept TIDs. Specifically,
the `lwp_setaffinity` function and related internal functions now
operate using thread IDs and adjust thread affinity settings accordingly

This change addresses a potential out-of-memory access issue in the
devfs filesystem component. The issue arises when the `rt_malloc`
function allocates memory for a path string without accounting for
the null terminator, leading to undefined behavior.
As the manual documented:
> DESCRIPTION
> The strlen() function calculates the length of the string pointed to
> by s, excluding the terminating null byte ('\0').
To fix this, the memory allocation size was increased by one byte
to ensure space for the null terminator. This prevents potential
out-of-memory access and ensures proper string termination.

* [thread] Add rt_thread_close()
This patch introduces a new function `rt_thread_close()` to enhances the
usability and maintainability by providing a dedicated mechanism for
closing threads.
- A new function `rt_thread_close()` is added to the API, providing a
standardized approach for closing threads.
- The `rt_thread_close()` function removes a thread from the thread
queue, updates its status to indicate closure, and performs the thread
timer detaching which is a embedded timer in thread object.
- Additionally, the `rt_thread_detach()` function is modified to utilize
`rt_thread_close()` internally, streamlining the thread detachment
process.

serial_v2驱动框架，rt_serial_tx_enable()函数，在 DMA阻塞发送(RT_DEVICE_FLAG_DMA_TX and RT_SERIAL_TX_BLOCKING) 的时候，使用rt_malloc分配了tx_fifo内存，但是并未对tx_fifo->rb.buffer_ptr指针进行初始化（rt_malloc不会自动初始化内存），因此可能导致buffer_ptr是一个随机指针。但是rt_serail_write()函数需要根据tx_fifo->rb.buffer_ptr是否为RT_NULL来判断是调用_serial_fifo_tx_blocking_nbuf()还是_serial_fifo_tx_blocking_buf()。
由于tx_fifo->rb.buffer_ptr可能是一个随机值（不一定为RT_NULL=0），导致RT_DEVICE_FLAG_DMA_TX and RT_SERIAL_TX_BLOCKING模式下调用了_serial_fifo_tx_blocking_buf()，但是rb没有真正开辟内存空间，导致内存异常
你的解决方案是什么 (what is your solution)
rt_serial_tx_enable()，在DMA阻塞发送分支下，对tx_fifo->rb.buffer_ptr进行初始化，赋值为RT_NULL。
