The previous init sequence relied on the display ignoring commands if
they are sent faster than 40us. Some displays may not have this
limit.
Rework the init to make it more robust to command transmission times.
The new init should still transition the display into 4-bit mode even
if the display processes commands faster than 40us.

Add get_status wrapper with last_query status for macros It is sometimes useful to determine the state of the probe from a macro. If the probe is connected to an endstop pin, the results can be obtained via QUERY_ENDSTOPS but if a physical endstop is in use in addition to the probe the probe state cannot be obtained. This change allows one to use QUERY_PROBE and then access the printer.probe.last_query object to obtain the state.

Arc travel was working but extrusion in absolute mode seemed not to be happening at all. This was because the E coord being sent with each G1 segment of the arc was not incrementing, effectively the same value was being sent over and over so the total extrusion for the whole arc was the amount for just one segment which is an extremely tiny amount.
My change increments e_base by e_per_move for each subsequent coord when in absolute extrude mode which results in the correct absolute E value being sent for each segment.
