Instead of waiting for a single long block, compare the complete block
buffer runtime for the long_move() check.

・Fix memory leak

Update Japanese translation

Introduce a +1234.56 format for over 999 steps/mm

・Change translation for 16 width LCD

Simply apply enabled settings instead of requiring users to edit
stepper_indirection.cpp

Endstop interrupt refinement

At the start of a move, check if the endstops are already triggered.
The 'change' interrupts will not see a change if already triggered.

Ensure smooth print moves even with LCD enabled

Re-follow the PR #4634 (Set language display charset in language.h)

lcd_update can take so much time that the block buffer gets drained if
there are only short segments. This leads to jerky printer movements for
example in circles and a bad print quality.

This change implements a simple check: Only if the block currently
executed is long enough, run lcd_update.
This also means the printer will not show actual values on the LCD nor
will it respond to buttons pressed. A option that keeps the menu
accessible is also available.
Aditionaly, slow down if a block would be so fast that adding a new
block to the buffer would take more time. In this case, the buffer would
drain until it's empty in worst case.

Added CMake support
