add BLTouch-related messages in english and (rusty) french;
add missing endstops.h in ultralcd.cpp;

- Japanese and Chinese still need update

MSG_INFO_PRINT_TIME is still being used

・Remove MSG_END_HOUR and MSG_END_MINUTE from all the language files
・Change from MSG_INFO_TOTAL_PRINTS to MSG_INFO_PRINT_COUNT in German
file

Make MAPPER_NON the fall back mapper - if no other is defined.
One list less to maintain.

・Remove abolished strings (MSG_NOZZLE1, MSG_NOZZLE2)
・Remove duplicated strings 
・Arrange the strings in unified order
・Adjust spacing
・Remove some comments in Japanese files(follow-up the PR #3560)

The most part of these changes were salvaged from closed my PR#3550.

In all these cases we want the axis to be homed. If we could have lost
some steps is secondary.

Reenables homing seperate axis with DISABLE_X / DISABLE_Y true.

Following up on #3231

documentation/LCDLanguageFont.md moved to http://www.marlinfirmware.org/ at commit 12d0983757,
but http://www.marlinfirmware.org/ isn't working.

Keep "astyled" reformatting

Apply `ENABLED` / `DISABLED` macros to language-related files.

* Added MSG_END_HOUR and MSG_END_MINUTE labels to all language files.
