[PATCH] platform/x86: hp-wmi: add Omen 16-wf0xxx (board 8BAB) fan & perf-profile support

[noahpro <noahpro@gmail.com>]

Recent 2024-era Omen laptops (DMI board 8BAB) use different
thermal-profile commands (0x48 default, 0x31 performance) but are very
similar to those used by the existing Victus-S code paths although
it wasn't in the config.  As a result:

- `/sys/devices/platform/hp-wmi/fan*` reported 0
- `echo 0 | sudo tee /sys/devices/platform/hp-wmi/hwmon/*/pwm1_enable`
  max-fan writes failed
- platform_profile was not registered, so performance/balanced switching
  was not available

I added the new board to victus_s_thermal_profile_boards[] and created
omen_2024_thermal_profile_boards[] with HP_OMEN_2024_THERMAL_PROFILE_*
enums, and switched the Victus-S performance setter to choose the
right wmi commands.

I was was unsure of whether to rename the victus_s_ names to
newer or 2024 boards everywhere becuase this would clutter the commit.

Tested on HP Omen 16-wf0xxx (BIOS F.21):
 * fan RPMs readable
 * performance/balanced switching works (needed nvidiaDynamicBoost to
   see max wattage changes but it does work)
 * "max fans" honoured (firmware reverts after 120 sec, but the existing
   timed board variables don't work when testing. On Windows the
   Omen Command Center simply sends lots of commands to keep this alive
   so this seems fine to me as user applications can write to the
   fan speed every ~100 sec).
