* Group status methods, share reset_status with Extensible UI
* Move common DOGM code to headers

In reference to #11000

- In reference to #12166

* Apply #pragma once in headers
* Adjust some thermistors formatting
* Misc cleanup and formatting

- Remove `print_job_timer.stop()` from `disable_all_heaters`
- Call `print_job_timer.stop()` for relevant `disable_all_heaters()`.
- Split up `kill()` for watchdog interrupt safety

- 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.

* 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

* Allow override of soft SPI pins in `pins_*.h`
* Add default case to avoid compiler warning.
* Additional pin definitions for Archim 2.
* Einsy Retro has same timings as Einsy Rambo.

With default config and `EEPROM_SETTINGS`, saves over 200 bytes of PROGMEM.

Prescalers aren't calculated for the given target frequency.
Stepper timer should run at 2 Mhz and temperature timer at 72 Khz.
