arch/tricore: drop illd dependence for atomic

[zhangyu-duck]

Summary

This PR removes the TriCore atomic implementation's dependency on ILLD intrinsics and switches to the NuttX arch-atomic backend.

Patch 1: arch/tricore: drop illd dependence for atomic

• Replace ILLD intrinsics (__swap, __ld32, __cmpAndSwap) with inline assembly functions (tricore_atomic_swap, tricore_atomic_cmpswap) in libs/libc/machine/tricore/arch_atomic.c
• Remove the #include <IfxCpu_Intrinsics.h> dependency
• Fix the expect parameter type to volatile void * to match the declaration in atomic.h

Patch 2: arch/tricore: use tricore arch-atomic-instruction version

• Select LIBC_ATOMIC_ARCH for TriCore when not using Tasking toolchain, so that the tricore arch-atomic implementation is used instead of the toolchain builtin

Testing

Tested with TC4 (TC4da) build with GCC toolchain.
