This PR is just about tuning the intermediate Idler positions so that the filament gets relieved from the Pulley safely while the Extruder gears take over and the activeSlot+1 filament is not affected by its Idler bearing.
On a test bench filament was creeping about 0.5mm per Toolchange.
Changing the intermediate position from exact middle into 3/4 practically elliminated the creep. We can play with these constants more if necessary in the future.

Unfortunately, there is no way to differentiate between an optimized gpio write (safe always on the atmega32u4) and an unoptimized write (read-modify-write, dangerous if any other pin on that Port is used in an ISR).
While very quickly polling the tmc registers, I noticed that the moving stepper would do some random extra steps. That can only be explained by the following sequence of actions:
- the spi code reads the PORT register
- ISR toggles the step line, changing the value in the PORT register
- the spi code writes the upated PORT back, resetting the step line to the old state
After making the writes atomic, the stepping issue disappeared and the driver checks also worked correctly
- rename stall*guard to StallGuard (match name with the vendor)
- separate TMC2130 module from EEPROM (they do not need to know about each other at all)
- separate SGTHRS settings from motion - moved to globals like all other "global" parameters
- improved EEPROM storage for SGTHRS
