Various fixes and improvements (#435)

- Fix for `sdkconfig` generation: the keys that contained the MCU type in its name weren't properly upper-cased.
- Moved WiFi configuration property files to the user data path of the app instead of a fixed location.
- Moved more properties from `device.py` to `sdkconfig/default.properties`
- Fix for `device.cmake` device id parsing: separate basic property parsing from device id validation
- Created internal `tt::service::wifi::findServiceContext()`
- Changed Wi-Fi service id to lowercase (will change it for other services later)
