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.

* [libcpu/arm64] add C11 atomic ticket spinlock
Replace the former implementation of flag-based spinlock which is unfair
Besides, C11 atomic implementation is more readable (it's C anyway),
and maintainable. Cause toolchain can use their builtin optimization and
tune for different micro-architectures. For example armv8.5 introduces a
better instruction. The compiler can help with that when it knows your
target platform in support of it.

* [src] add rt_hw_cpu_id() wrapper API
rt_hw_cpu_id() is an unsafe API which should not be used by most codes
directly. It's error-prone because it must be used in proper context,
otherwise it can lead to errors and unpredictable behavior.
This patch adds a wrapper API for rt_hw_cpu_id() to address this risk.
It includes the context-checking functionality and provides a safer
alternative for obtaining CPU IDs, ensuring that it is used correctly
within the appropriate context.
