Gimbal speed auto fov

[Niki-dev12]

Auto-adjust gimbal FOV and zoom-dependent control
Description

This change requests updated camera field-of-view (FOV) information from the vehicle whenever the gimbal zoom level changes.
By using CAMERA_FOV_STATUS, QGC dynamically updates the horizontal and vertical FOV values and adjusts the click-to-point gimbal movement accordingly. When zoomed in, the gimbal motion becomes finer and moves a shorter distance per click, improving precision.

In addition, pitch and yaw rate limits are scaled based on zoom level to maintain smooth and intuitive control.

Test Steps

1. Connect to a drone equipped with a zoom gimbal.
2. Enable click-to-point functionality in Gimbal Settings.
3. Change the zoom level.
4. Verify that HFOV/VFOV values update automatically.
5. Click on the video stream and confirm that gimbal motion becomes more precise at higher zoom levels.
