[2.0.x] DUE - native port hang (USB CDC: Do not send any character if no program on the PC is listening)

Some users may prefer to hide the position updates on the `LIGHTWEIGHT_UI` altogether. This leads to an even less cluttered display (it also saves on SPI traffic and one byte of RAM).

[2.0.x] Clean up Trinamic config options, sanity check

[2.0.x] DUE - add programming capability to native port

[2.0.x] platformio.ini - add DUE native port support

Fixes #10071

Some probes don't work near the edges of the bed. This change promotes MIN_PROBE_EDGE to a general setting that applies to all probing functions.

Followup to #7914

Some "fix-mounted" probes need manual stowing. And after probing some may prefer to raise or lower the nozzle. This restores an old option but tailors it to allow raise or lower as preferred.

`M204` is often used by slicers to set acceleration depending on perimeter, infill, etc., so Marlin's answers are flooding the serial windows. Silence `M204` according to the philosophy that setter commands should only send a reply if no parameter is given.

[2.0.x] Add UNKNOWN_Z_NO_RAISE to prevent Z grinding

[2.0.x] DUE compatibility with shared SPI LCDs, USB mass storage, add pin defs & update examples\MakerParts\Configuration.h

With this option enabled, Z won't ever be raised until after `G28` has been completed, and it won't raise if Z becomes unknown. This is good for machines whose beds fall when Z is powered off.

…and limit the raise to Z_MAX_POS
