platform/x86: hp-wmi: add manual fan control for Victus S models

Add manual fan speed control and PWM reporting for HP Victus S-series
laptops.

While HPWMI_FAN_SPEED_SET_QUERY was previously added to reset max fan
mode, it is actually capable of individual fan control. This patch
implements hp_wmi_fan_speed_set() to allow manual control and hides
PWM inputs for non-Victus devices as the query is Victus specific.

The existing hp_wmi_fan_speed_max_get() query is unreliable on Victus S
firmware, often incorrectly reporting "Auto" mode even when "Max" is
active. To resolve this synchronization issue, move state tracking to
a per-device private context and apply "Auto" mode during driver
initialization to ensure a consistent starting point.

Refactor hp_wmi_apply_fan_settings() to use an intermediate ret
variable. This prepares the switch block for keep-alive logic being
added in a later patch, avoiding the need for duplicated mode check.

Tested on: HP Omen 16-wf1xxx (board ID 8C78)
