[1.1.x] Add option for NO_VOLUMETRICS

[thinkyhead]

As requested in #8232

With NO_VOLUMETRICS enabled the G-code M200 will be left out of the build along with all other volumetric extrusion-related code.

[CCS86]

Hey @thinkyhead, I tried enabling NO_VOLUMETRICS and get the following compile error. Are there other required code changes?

ultralcd.cpp:3638: error: 'class Planner' has no member named 'filament_size'

MENU_MULTIPLIER_ITEM_EDIT_CALLBACK(float43, MSG_FILAMENT_DIAM, &planner.filament_size[0], 1.5, 3.25, planner.calculate_volumetric_multipliers);

@CCS86 — That is already patched in bugfix-1.1.x apparently.
