add MACHINE_KINEMATICS to M115

[ellensp]

Description

Add the machines kinematics to M115
Why? so when you ask the a user did you enable (COREXY, COREZX, SCARA etc) and they respond, "I don't know"
M115 can tell them if the firmware they are running has the required kinematics.

Requirements

M115

Benefits

Visibility of the selected compiled in kinematics.

Related Issues

Had a user on Discord having issue with their COREXY moving diagonally. They had not enabled COREXY on their corexy
M115 could have confirmed this quickly.

I made some minor adjustments. Use of TERN_ to make the code smaller. And since BELTPRINTER is also CoreXY (but could be something else) I put BELTPRINTER last as an add-on. Maybe a more general suffix like "(Infinite Z)" would be better. But the host can get the size of the Z axis from the Geometry Report, and there might be other things it can do with a "belt" printer, such as setting the number of times to loop through the print, or implementing M808 on the host side.
