There was a problem hiding this comment.
Seems mostly based on already existing gyro code but SDL2 handles system and joystick gyros separately, so maybe it's fine for now.

Renamed the cl_gyro cvar to gyro_enable, and updated other cvars starting with cl_gyro_ to gyro_, following the naming convention of touch_ and joy_ cvars |

Introduce native support for mobile gyroscope sensors using the SDL2 Sensor API, enabling player view and aiming control with the built-in gyroscope on Android, iOS, and other SDL2-compatible platforms.
The implementation is split into platform-agnostic logic in
engine/client/in_gyro.cand a platform-specific sensor layer inengine/platform/sdl2/sensor_sdl2.c.Axis mapping is pre-configured for landscape orientation, typical for mobile gaming.
New CVars
gyro_enable: Master toggle for the built-in gyroscope.
gyro_available (Read-only): Hardware status indicator.
gyro_pitch, gyro_yaw, gyro_roll: Individual axis sensitivity.
gyro_pitch_deadzone, gyro_yaw_deadzone, gyro_roll_deadzone: Configurable thresholds to eliminate sensor jitter and noise.
