Qtvcp -improve basic/versa probe based on testing/feedback

Squashed a bunch of commits:

qtvcp -probe routines: don't add extra depth to down probing
extra depth should be only for side probing

qtvcp -probe routines: add better error messaging, common timeout variable
can set MDI timeout in one place - im future maybe from screen code.
can mow send error messages with more context - probe_down is an example
can pass linuxcnc error to screen ie command timeout/probe finished without contact
Neesa lots of error message context added for other probe functions but this is a start

qtvcp -versa probe help: larger images, more use details

qtvcp -probe routines: fix reporting of outside diameter of probed boss
couldn't calculate diameter because outsie boss probing used
other probe function which did not report lengths back in a way we could have used.
or at least I think so - some data uses global reference so maybe it woulda worked.
this is just easier on my brain.
really just copied probe_outside_length_x and probe_outside_lenmgth_y code
into a new function that adds the diameter calculation

qtvcp -probe routines: adjust numeric format on inch/metric machines
inch needs 4 places, metric need 3

qtvcp -versa/basic probe: report details in statusbat if available

qtvcp -probe routines: improve hole probe error messages and small hole probing.
in small holes it will skip the rapid positioning if required.
Does some basic error calculation checks, such as probe diameter vrs hole diameter and
max probe travel vrs hole diameter.

qtvcp -probe routines: add checks for missing required hints
