gcode: Remove support for the M206 command 

The M206 command isn't particularly standardized and isn't issued by
default from 3rd party software in their standard configurations.
Encourage users to use the more powerful SET_GCODE_OFFSET command.

# Changes
20191210: Support for the M206 command has been removed. Replace with
calls to SET_GCODE_OFFSET. If support for M206 is needed, add a
[gcode_macro M206] config section that calls SET_GCODE_OFFSET. (For
example "SET_GCODE_OFFSET Z=-{params.Z}".)
20191202: Support for the undocumented "S" parameter of the "G4"
command has been removed. Replace any occurrences of S with the
standard "P" parameter (the delay specified in milliseconds).

The following standard G-Code commands are currently available, but
using them is not recommended:
- Offset axes: `M206 [X<offset>] [Y<offset>] [Z<offset>]` (Use
SET_GCODE_OFFSET instead.)
- Get Endstop Status: `M119` (Use QUERY_ENDSTOPS instead.)
