Modify the kernel to use only atomic_xx and atomic64_xx interfaces,
avoiding the use of sizeof or typeof to determine the type of
atomic operations, thereby simplifying the kernel's atomic
interface operations.

After compilation, when starting nsh, the following crash occurs.
==2500151==Shadow memory range interleaves with an existing memory mapping. ASan cannot proceed correctly. ABORTING.
==2500151==ASan shadow was supposed to be located in the [0x1ffff000-0x3fffffff] range.
==2500151==Process memory map follows:
0x30000000-0x33dd4000 /nuttx/nuttx
To avoid overlaps, change the starting address of the text segment.
Using Ttext-segment=0x30000000 causes a crash when starting the 32-bit SIM.
Using -Ttext-segment=0x50000000 causes a crash when starting the 64-bit SIM.
Setting -Ttext-segment=0x40000000 resolves all issues perfectly.

reason:
When entering an exception or interrupt, there are two sets of registers:
one is the "running regs", which we need to save,
and the other is the "ready to running regs", which we may soon use.
For consistency in logic, we can always store the "running regs" in the regs field of g_running_tasks,
otherwise it may lead to errors in the storage location of the "running regs."
When we need to access the "running regs," we should uniformly retrieve them from the regs field of g_running_tasks.
As the next step, we will rename the set_current_regs/up_current_regs functions
for each architecture to more appropriate names, solely for the purpose of identifying interrupts.

2. Since llvm profile supports more than just gcov, and some features have not yet been explored, two clang gcov implementations are supported after this patch
3. Using this lib only supports the gcov compilation options of "-fprofile-instr-generate -fcoverage-mapping"
4. This file is heavily dependent on the compiler clang version, and is currently aligned with ci, supporting 17.0.1 and below. 18 and above are not supported by this library due to different internal implementations of the compiler

The reason for removing math.h is that undefining __GLIBC__ does not take effect. By default, sim will use the toolchain's math library and undef __GLIBC__ in the source file.

The default heap management in nuttx returns a valid memory address when malloc(0).
In sim_heap, malloc(0) returns NULL, aligning the behavior of sim_heap with mm_heap
The man manual describes malloc as follows:
https://man7.org/linux/man-pages/man3/malloc.3.html
The malloc() function allocates size bytes and returns a pointer
to the allocated memory. The memory is not initialized. If size
is 0, then malloc() returns a unique pointer value that can later
be successfully passed to free(). (See "Nonportable behavior"
for portability issues.)
