Merge develop into main (#316)

- Updated all boards to use `hal::Configuration.createDevices`
- Updated all boards to use new directory structure and file naming convention
- Refactored `Xpt2046SoftSpi` driver.
- Created `Axp2101Power` device in `Drivers/AXP2101`
- Removed global static instances from some drivers (instances that kept a reference to the Device*)
- Improved `SystemInfoApp` UI: better memory labels, hide external memory bar when there's no PSRAM
- Fix for HAL: register touch devices after displays are registered
- Fix for Boot splash hanging on WiFi init: unlock file lock after using it
