Fix kill() and ExtensibleUI (#12160)

* Fix to isPrintingFromMedia()

  - isPrintingFromMedia() will now return true even if SD print is paused.
  - isPrintingFromMediaPaused() allows UI to determine if the print is paused.

* Don't use _delay_us in minkill (#12145)

  - In HAL_DUE, _delay_us is simply an alias for delay, which causes the board to hang and subsequently reboot due to the watchdog timer.

* Shorten code with IFSD macro
