Allow positive Z nozzle to probe offset (#20344)

Browse Source 
* Allow a positive value for z offset from nozzle to probe without sanity checks
* Simplify menu_probe_offset.cpp (HOMING_Z_WITH_PROBE)
* Add some more explanation to Configuration Files
* Raise after probe_at_point as if homed

/**
* Nozzle-to-Probe offsets { X, Y, Z }
*
* - Use a caliper or ruler to measure the distance from the tip of
* X and Y offset
* Use a caliper or ruler to measure the distance from the tip of
* the Nozzle to the center-point of the Probe in the X and Y axes.
*
* Z offset
* - For the Z offset use your best known value and adjust at runtime.
* - Probe Offsets can be tuned at runtime with 'M851', LCD menus, babystepping, etc.
* - Common probes trigger below the nozzle and have negative values for Z offset.
* - Probes triggering above the nozzle height are uncommon but do exist. When using
* probes such as this, carefully set Z_CLEARANCE_DEPLOY_PROBE and Z_CLEARANCE_BETWEEN_PROBES
* to avoid collisions during probing.
*
* Tune and Adjust
* - Probe Offsets can be tuned at runtime with 'M851', LCD menus, babystepping, etc.
* - PROBE_OFFSET_WIZARD (configuration_adv.h) can be used for setting the Z offset.
*
* Assuming the typical work area orientation:
* - Probe to RIGHT of the Nozzle has a Positive X offset
