Add board MKS_BASE_HEROIC (#9924)

Browse Source 
Followup to #9008

- Don't define micro-stepping pins for boards that lack them.
- Allow setting of 128 microsteps with `M350`.

// But the Heroic has a 128 µStepping mode where the A4982 is doing quarter steps (MS1=L / MS2=H). To achieve comfortable tests with the M350/M351 commands, the following definitions have to made:
// Example: M350 X4 Y4 ; Set X and Y Axis to quarterstep Mode to achieve MS1=0 and MS2=1
// A new board with a HR4982 will now perform 128 µSteps per Fullstep
// XSTEP,YSTEP ... must be adapted with M92 accordingly (128/16 => multiply by factor 8).
