feat: [libcpu/c906] support ARCH_REMAP_KERNEL
This change was necessary to enable the remapping of the kernel image to
a high virtual address region on the c906 platform.
Changes:
- Introduced new configuration options `ARCH_REMAP_KERNEL`, and
`ARCH_USING_ASID` under the `ARCH_RISCV64` section.
- Updated MMU initialization and switching functions to incorporate
remapping handling.
- Modified page table setup for proper memory attribute settings.
- Added support for early memory setup, kernel remapping
- Added conditional compilation for ASID support in the `rt_aspace` struct,
since this is not enable currently for most architecture.

Skip configure on open since all configs are copied from the current
configuration on device. So we don't bother to set it back to device
again.
Changes:
- test and skip configuration on open() of tty device

* [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.

* [utest] remove delay for on thread testing
The delay is introduced from 0dc7b9a5a26030a945723569c64f5be46bd70ae1.
Though this is unnecessary for on sync utest.
So this is removed by a new entry and delay for asynchronous utest only.

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
