* Fix Z value display
* Add HAS_PRINT_PROGRESS
* Alternative Info Screen option
* Add LCD_INFO_SCREEN_STYLE to example configs

- Fix an error in the return value of `sd_mmc_spi_read_capacity` which was causing the host OS to read beyond the last sector in the card.
- Clean up the USB flashdrive code and add better debugging.

- Enable filament change menu
- Enable bed-PID
- Enable s-curve acceleration
- Enable some menu items
- Update from Skorpi's new version
- Fix extruder steps, deactivate nozzle clean feature

* Universal tool-change Z lift
* Add TOOLCHANGE_ZRAISE to example configs
* Park/unpark changes to example configs
* Implement DEBUG_DXC_MODE

- Add methods to access print counter data
- Clean up some inconsistent method names
- Clear lcd status after filament change
- Implement `lcd_reset_status` so it works like UltraLCD

- Added FILAMENT_RUNOUT_DISTANCE_MM option
- Added FILAMENT_MOTION_SENSOR option

Homing on the Ender 3 with HOMING_FEEDRATE_XY set to 50*60 was shown (#12074) to cause the end-stop micro-switches to bottom out, causing the carriage for both X and Y axis to physically crash into the micro switch. Reducing the homing speed prevents the switches from bottoming out.

* Add traceback after watchdog timeout

Add the cpability to perform a traceback following a watchdog timeout.

* Enhanced hardware SPI

Allow use of either SSP0 or SSP1.
Ensure that no data is left in I/O buffers after calls to enable sharing of SSP hardware.

* Make flash emulation of eeprom the default

Make use of flash for eeprom storage the default. This means that usage of eeprom will not cause USB drive mount/unmount operations.

* Allow sharing of SD card

SD card I/O operations from the USB stack take place in idle loop, rather than at interrupt time. Allowing sharing of the SPI bus.

New configuration options to allow usage of the SD card to be specified.

* Fix problem with hardware SPI pins
