The Configuration.h file entries for BL-Touch have been updated to:
```cpp
//#define BLTOUCH
//#define BLTOUCH_DELAY 375      // (ms) Enable and increase if needed
//#define BLTOUCH_HEATERS_OFF // if defined the printer's heaters are
turned off during probe event
```

==============================================

clarified BLTouch calculation & changed comment delimitters/flags

I found it hard to pickout the various sections in this area so I
changed most comments from // style to /** ... */

Made the BLTouch calculation simpler and clarified the units of measure
for the result.

============================================

add changes to example configurations

============================================

add TinyBoy2 to this PR & add BLTouch Delay

The OLED is driven by an SSD1306, connected to the board via
I2C, the rotary encoder is connected to 3 GPIO pins.

- Add configuration support for zigzags in either the X or Y axis, for
wipe pads significantly longer in one dimension.
- Add configuration for default number of zig-zag triangles, vs. a
magic number in `Marlin_main.cpp`.
- Update description of auto nozzle wiping to match functionality

delay() is milliseconds

`Z_MIN_ENDSTOP_INVERTING` must match `Z_MIN_PROBE_ENDSTOP_INVERTING`
when using `Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN`.
This is easy to overlook.

- Fix typos, verbiage
- Fix naming of `setup_endstop_interrupts`
- Some formatting, indentation, spacing
