extruder: Deprecate old extruder commands and shared_heater config option 

Deprecate SET_EXTRUDER_STEP_DISTANCE and SYNC_STEPPER_TO_EXTRUDER.
Recommend using SET_EXTRUDER_ROTATION_DISTANCE and
SYNC_EXTRUDER_MOTION.

Deprecate the extruder "shared_heater" option and reocmmend using
extruder_stepper config sections to obtain the same functionality.

## Changes
20220210: The `SYNC_STEPPER_TO_EXTRUDER` command is deprecated; the
`SET_EXTRUDER_STEP_DISTANCE` command is deprecated; the
[extruder](Config_Reference.md#extruder) `shared_heater` config option
is deprecated. These features will be removed in the near future.
Replace `SET_EXTRUDER_STEP_DISTANCE` with
`SET_EXTRUDER_ROTATION_DISTANCE`. Replace `SYNC_STEPPER_TO_EXTRUDER`
with `SYNC_EXTRUDER_MOTION`. Replace extruder config sections using
`shared_heater` with
[extruder_stepper](Config_Reference.md#extruder_stepper) config
sections and update any activation macros to use
[SYNC_EXTRUDER_MOTION](G-Codes.md#sync_extruder_motion).
20220116: The tmc2130, tmc2208, tmc2209, and tmc2660 `run_current`
calculation code has changed. For some `run_current` settings the
drivers may now be configured differently. This new configuration

#### SET_EXTRUDER_STEP_DISTANCE
`SET_EXTRUDER_STEP_DISTANCE EXTRUDER=<config_name>
[DISTANCE=<distance>]`: Set a new value for the provided extruder's
"step distance". The "step distance" is
`rotation_distance/(full_steps_per_rotation*microsteps)`. Value is not
retained on Klipper reset. Use with caution as small changes can
result in excessive pressure between extruder and hot end. Do proper
calibration with filament before use. If 'DISTANCE' value is not
included command will return current step distance.
This command is deprecated and will be removed in the near future.
#### SYNC_STEPPER_TO_EXTRUDER
`SYNC_STEPPER_TO_EXTRUDER STEPPER=<name> EXTRUDER=<name>`: This
command will cause the given extruder STEPPER (as specified in an
[extruder](Config_Reference#extruder) or
[extruder stepper](Config_Reference#extruder_stepper) config section)
to become synchronized to the given EXTRUDER. If EXTRUDER is an empty
string then the stepper will not be synchronized to an extruder.
This command is deprecated and will be removed in the near future.
