Fix DIRECT_MIXING_IN_G1 to preserve the previous mix

bump -std in Makefile to c++11

Fix G30 with limits, print correct probe XY

still a few bytes bigger than with arduino but nothing major

needed for constexpr

Store mix factors as reciprocals and multiply

Extended host support: M155 Auto temp report, M115 capabilities

Follow up the PR #5167 (Add Turkish Language) again, etc

Remove useless line from stepper ISR

Megatronics 3.0 has no SD-Card detect

The flag is already set inside planner.get_current_block(). Doing it
twice isn't making it better..

・Update forgotten K8400\Dual-head\Configuration.h
・Adjust spacing

Give instant feedback for filament change

Improve G30 probing command - add optional arguments

Follow up the PR #5167 (Add Turkish Language), etc

・Add new translation

・Remove all the #ifndef
・Follow the PR #4603 (Strip never-translated strings from language
files)
・Follow the PR #4634 (Set language display charset in language.h)
・Follow the PR #4936 (Put max_jerk vars in array, clean up jerk code)
・Adjust spacing

Add Turkish Language

Add optional parameters
X, Y for probe point
S sets stowing on and off

BABYSTEPPING-oriented cleanup

OLD_SLOWDOWN does nothing, so remove it

Account for wipe moves

Don't define bilinear_line_to_destination on kinematic setups

Added a rule so that LIN_ADVANCE isn't used for moves with negative E movements (de_float will be negative in this cases).
I also added a more detailed comment to make it more clear what the if statement does.

Corrections to bilinear_line_to_destination

- Allow more than 9x9 probe points
- Account for the probe starting position

Fix Z raise with DXC_AUTO_PARK_MODE
