Merge develop into main (#391)

## Improvements

- Created new base driver classes: `EspLcdDisplayV2' and `EspLcdSpiDisplay`
- Updated `St7789Display` to implement `EspLcdSpiDisplay`
- Updated all boards with ST7789 display

## Fixes

- Ensure that `tmp/` is created on startup (for all writeable filesystems)
- Fix for `lv_list` padding on small screen devices
- Fix for `PreferencesEsp` not processing result when writing string to NVS

## Other

- Remove unused build scripts
