ice: add fw and port health reporters

Firmware generates events for global events or port specific events.

Driver shall subscribe for health status events from firmware on supported
FW versions >= 1.7.6.
Driver shall expose those under specific health reporter, two new
reporters are introduced:
- FW health reporter shall represent global events (problems with the
image, recovery mode);
- Port health reporter shall represent port-specific events (module
failure).

Firmware only reports problems when those are detected, it does not store
active fault list.
Driver will hold only last global and last port-specific event.
Driver will report all events via devlink health report,
so in case of multiple events of the same source they can be reviewed
using devlink autodump feature.

$ devlink health

pci/0000:b1:00.3:
  reporter fw
    state healthy error 0 recover 0 auto_dump true
  reporter port
    state error error 1 recover 0 last_dump_date 2024-03-17
	last_dump_time 09:29:29 auto_dump true

$ devlink health diagnose pci/0000:b1:00.3 reporter port

  Syndrome: 262
  Description: Module is not present.
  Possible Solution: Check that the module is inserted correctly.
  Port Number: 0
