net: napi: add CPU affinity to napi->config

Move the IRQ affinity management to the napi struct. All drivers that are already using netif_napi_set_irq() are modified to the new API. Except mlx5 because it is implementing IRQ pools and moving to the new API does not seem trivial. Tested on bnxt, ice and idpf. --- Opens: is cpu_online_mask the best default mask? drivers do this differently v2: - Also move the ARFS IRQ affinity management from drivers to core. Via netif_napi_set_irq(), drivers can ask the core to add the IRQ to the ARFS rmap (already allocated by the driver). RFC -> v1: - https://lore.kernel.org/netdev/20241210002626.366878-1-ahmed.zaki@intel.com/ - move static inline affinity functions to net/dev/core.c - add the new napi->irq_flags (patch 1) - add code changes to bnxt, mlx4 and ice.
