GPS: Performance improvment for U-Blox hardware

[D4rk4]

In this Pull Request, I propose improvements to our devices' Global Navigation Satellite System (GNSS) performance by adapting the navigation engine's configuration.

Here are the key changes:

• Switching to GPS + SBAS (Satellite-Based Augmentation System) + GLONASS for enhanced stability. By leveraging multiple satellite systems, we can ensure more robust satellite coverage and mitigate the effects of signal blockages or interferences that might occur in certain environments.
• Enabling the AssistNow Autonomous feature. This allows the GNSS module to predict satellite positions based on previously collected ephemeris data, which in turn helps to reduce the Time-To-First-Fix (TTFF). It offers better performance in weak signal conditions and helps to achieve a faster startup.
• Turning on the anti-jamming feature. This adds an extra layer of protection to our GNSS module by making it more resilient to intentional or unintentional radio-frequency interferences, hence ensuring a consistent GNSS performance.
• Making sure the new configuration persists across reboots.

By integrating these improvements, I am confident that the GNSS performance of our devices will be significantly enhanced, leading to better stability, faster TTFF, and more reliable functionality under varying signal conditions.

Please review these changes and provide your feedback. These adjustments will greatly contribute to the system's performance and reliability.

Did you make sure to use Trunk? That was causing my checks to fail because of formatting issues and therefore build failures.

Great PR, if we can clean it up a bit it can go in!

@D4rk4 Which Ublox chips does it work for exactly? Were you able to notice any performance improvements in the real world?
