Execute DOGM display-loop less often

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 6361404b.

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
