OpenMW Android 0.51.0-13

PowerVR Fix

• Fixed invisible hands and weapons in first-person view on devices with a PowerVR GPU (e.g. Google Pixel 10/11 and many MediaTek Helio phones). The weapon was visible in third person, but nothing was drawn in first person.
• Android Automotive build: minimum Android version raised to 7.0 (API 24) for Google Play. No Android Automotive device is affected, and the regular APK still supports Android 5.0+.
