probe: Move multi-sampling capability from ProbePointsHelper to Probe

This changes the config file so that the configuration of
multi-samples is now done in the [probe] (and [bltouch]) section
instead of the various delta, bed_mesh, z_tilt, etc. config sections.

With this change, PROBE and PROBE_CALIBRATE commands now also utilize
multi-sampling.
