locking/atomics: Provide the arch_atomic_ interface to generic code
Architectures with instrumented (KASAN/KCSAN) atomic operations natively provide arch_atomic_ variants that are not instrumented. It turns out that some generic code also requires arch_atomic_ in order to avoid instrumentation, so provide the arch_atomic_ interface as a direct map into the regular atomic_ interface for non-instrumented architectures.
