softirq/core: Consolidate default local_softirq_pending() implementations
Consolidate and optimize default softirq mask API implementations. Per-CPU operations are expected to be faster and a few architectures already rely on them to implement local_softirq_pending() and related accessors/mutators. Those will be migrated to the new generic code.
