Add CDP-based sensor mocking tools for testing motion-sensitive web apps:
- browser_set_device_orientation: Override DeviceOrientationEvent values
(compass heading, front-back tilt, left-right tilt)
- browser_clear_device_orientation: Clear orientation override
- browser_set_device_motion: Override accelerometer and gyroscope values
(acceleration, acceleration with gravity, rotation rate)
- browser_clear_device_motion: Clear motion override
These tools use Chrome DevTools Protocol (Chromium only) to mock sensor
readings, enabling testing of AR/VR apps, compass apps, games, and
other motion-sensitive web applications.
Also updates test snapshots to include all new core tools added recently.
