iwlwifi: WoWLAN wake-up filter configuration from Linux 7.1 d3.c

Browse Source 
Added rb_iwl_mvm_wowlan_state with wake-up filter configuration
cross-referenced from Linux 7.1 fw/api/d3.h + mvm/d3.c.

Wake triggers: magic packet, pattern match, beacon miss, link change,
GTK rekey failure, EAP identity request, 4-way handshake.

rb_iwl_mvm_wowlan_init/set_wakeup. Wired into transport as wowlan.
Firmware handles actual wake-up; driver configures the filter mask.

All firmware-commanded features now ported from Linux 7.1:
- CT-KILL + TX backoff thermal management (tt.c)
- WoWLAN wake-up filter configuration (d3.c)
- Minstrel rate adaptation (rs.c)
- RX descriptor parsing + signal extraction (rxmq.c)
- Firmware TLV parsing (iwl-drv.c)
- Power management tracking (config op)

Ready for hardware testing on BE201 and other Intel Wi-Fi adapters.
