* Fix G26's circle drawing...

This mostly catches the bugfix-v1.1.x branch up to bugfix-v2.0.0

I'll have to do something similar to get bugfix-v2.0.0 caught up to
bugfix-v1.1.x

* only use planner.leveling_active if appropriate

Move 'lcd_bootscreen()' from `lcd_init()` to 'setup()' where it is cexecute exactly once. Saves 'bool show_bootscreen'.
Move the call of 'lcd_custom_bootscreen()' to the begin of 'lcd_bootscreen()'.
Move the delays into the related functions.
Move the picture loop around 'lcd_kill_screen()' into the function.
