Add support for the Fn+P hotkey found on newer HP Victus (and probably
newer Omen) laptops. This hotkey is intended for use with Omen Gaming Hub
to change the performance profile (see [1]).

Pressing Fn+P under linux produced the following warning in dmesg:

> hp_wmi: Unknown event_id - 27 - 0x7

Implemented a handling for this event so that the hotkey cycles between the
platform profiles when triggered.

Tested on Victus 16-s1011nt (9Z791EA, MB 8C9C).

Changes in v2:
- Make the key just switches between platform profiles instead of
  assigning a key event code. 
- v1: https://lore.kernel.org/all/20250802213541.18791-2-edip@medip.dev/

Thank you for your contribution, it has been applied to my local
review-ilpo-fixes branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-fixes branch only once I've pushed my
local branch there, which might take a while.
