tmc: SET_TMC_FIELD VELOCITY

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

#### SET_TMC_FIELD
`SET_TMC_FIELD STEPPER=<name> FIELD=<field> VALUE=<value>`: This will
alter the value of the specified register field of the TMC driver.
`SET_TMC_FIELD STEPPER=<name> FIELD=<field> VALUE=<value> VELOCITY=<value>`:
This will alter the value of the specified register field of the TMC driver.
This command is intended for low-level diagnostics and debugging only
because changing the fields during run-time can lead to undesired and
potentially dangerous behavior of your printer. Permanent changes
should be made using the printer configuration file instead. No sanity
checks are performed for the given values.
A VELOCITY can also be specified instead of a VALUE. This velocity is
converted to the 20bit TSTEP based value representation. Only use the VELOCITY
argument for fields that represent velocities.
