Remove unused ALARM_PIN from all the Configuration.h's

Keep "astyled" reformatting

* Updates the auto bed leveling comments ONLY.
* Renames "Z probe" word usage in //comments and #errors properly.

- `SD_DETECT_PIN` replaces `SDCARDDETECT`
- `SD_DETECT_INVERTED` replaces `SDCARDDETECTINVERTED`
- Revise the description of `SD_DETECT_INVERTED`
- Add a note about the override of `SD_DETECT_INVERTED` in
`Conditionals.h`

- Rename the pin so it can be tested with `PIN_EXISTS`
- Fix some incorrect tests for `SDCARDDETECT`

Apply `ENABLED` / `DISABLED` / `HAS_SERVOS` macros to pins files.

The instruction say to set a #define in fastio.h
However, that value is not included before this test.
