Ability to specify `VELOCITY` as a parameter for SET_TMC_FIELD. Useful for configuring at runtime the TSTEP based fields of the driver.

`multistep_filt` was not configured at all on tmc2240 and tmc5160. As such, it would default to the value of 0 when the GCONF field was sent to the driver. However, that field has a default value of 1 in the driver, so klipper was overriding the defaults by accident.
This field improves the stability of velocity based thresholds (it's effectively TSTEP filtering) and it also improves the current regulation stability in stealthchop2 (according to the datasheet).
This field was already set to 1 correctly in the tmc2208/tmc2209 driver code.
