heaters: Change default smooth_time from 2 seconds to 1 second

Browse source 
A larger smooth_time results in a slower reaction time for the PID.
This increased delay can cause temperature oscillations with high
power heaters.  Many boards produce good results without any
smoothing.  So, it seems a smooth_time of 1 second is a better
default.

## Changes
20210903: The default [`smooth_time`](Config_Reference.md#extruder)
for heaters has changed to 1 second (from 2 seconds). For most
printers this will result in more stable temperature control.
20210830: The default adxl345 name is now "adxl345". The default CHIP
parameter for the `ACCELEROMETER_MEASURE` and `ACCELEROMETER_QUERY` is
now also "adxl345".
