Fix for thePR #5267 (Introduce a +1234.56 format for over 999 steps/mm)

Minor stepper cleanup

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

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

If the stepper ISR takes too long, chars are lost which leads to serial
communication errors like "Line number not +1" or "Wrong checksum". In
worst case, the printer can even do crazy moves.

With this changes, UART interrupts are handled inside the stepper ISR.
This way, no chars should be lost.

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
