Fixed scara directions

Config said for a delta instead of for a scara

Fix bad thermal runaway trigger

In 'if (encoderPastThreshold || LCD_CLICKED)' lcdDrawUpdate was not set.

'lcd_status_update_delay'-loop was not effective in  function
lcd_status_screen().
The loop prevented the update of the status screen but not the displays
update.
Shifted the loop into lcd_update().

This reverts commit 6361404b91.

Shifted condition should still be in.

Dot is moving not so fast -> less executed loops.

Result see: https://www.youtube.com/watch?v=tdu7J0i-c4g
Loop is executed several times per display update.

Compare indices instead of floats for probe actions

Deferring default definition made #undef unnecessary

Optimize coordinate copying, fix EXTRUDER_RUNOUT_PREVENT

Z_PROBE_ENDSTOP Pin for Azteeg X3 Pro

- Document `manage_inactivity` function
- Allow `EXTRUDER_RUNOUT_PREVENT` to work with all extruders
- Use faster `memcpy` for copying coordinates

Minor optimizations

Compiling error temperature.cpp with multiple extruders defined

Just a simple #ifdef Z_PROBE_ENDSTOP to define the pin for it. Also has
a couple commented lines for switching Z_MIN_PIN if needed.

It wouldn't compile because of this line in temperature.cpp it turns out
it was just a stray ( that didn't line up with the previous lines so I
just made it in line with the rest and it compiled fine.

Fix: thermal_runaway_protection triggered by target temperature increase

Add PIDTEMPBED to EEPROM
