Following up on #3231

Based on #2860 - rebased for RCBugFix

Remove unused ALARM_PIN from all the Configuration.h's

Keep "astyled" reformatting

- `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`

For consistency with other pins, allowing use of `PIN_EXISTS` macro.

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

I added in the pins into the new board files for the Azteeg X3, X3 Pro,
Printrboard, and Rambo. I'm sure it can be added for others too but
these are the manual specified pins. Just like many things here though,
I can't test for the boards other than the Azteeg X3 Pro. Hopefully it
works smoothly for everyone who happens on this nifty display. :)

Hopefully this is helpful to organization and future expansion….
