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

* [libcpu] arm64: Add hardware thread_self support
This patch introduces hardware-based thread self-identification
for the AArch64 architecture. It optimizes thread management by
using hardware registers to store and access the current thread's
pointer, reducing overhead and improving overall performance.
Changes include:
- Added `ARCH_USING_HW_THREAD_SELF` configuration option.
- Modified `rtdef.h`, `rtsched.h` to conditionally include
`critical_switch_flag` based on the new config.
- Updated context management in `context_gcc.S`, `cpuport.h`
to support hardware-based thread self.
- Enhanced `scheduler_mp.c` and `thread.c` to leverage the new
hardware thread self feature.
These modifications ensure better scheduling and thread handling,
particularly in multi-core environments, by minimizing the
software overhead associated with thread management.

1.Mount the rootfs options by parameters:
- root=: root device, like vda1, sda1, sd0p1, nvme0n0p1...
- rootfstype=: root file system type, like elm, ext, crom...
- rw/ro: root is readonly or all enable, if not have 'rw' flag,
the 'ro' flag is default.
- rootwait: always wait for root device status is OK.
- rootdelay=: mount rootfs delay amount of time (millisecond).
2.Mount the other fs options by `fstab.sh`, it will read the script

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.
