* 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
- Remove `print_job_timer.stop()` from `disable_all_heaters`
- Call `print_job_timer.stop()` for relevant `disable_all_heaters()`.
- Split up `kill()` for watchdog interrupt safety
Some STM32-based boards may use multiplexed JTAG pins as IO. Up to now the `DISABLE_JTAG` option (defined in pins files) was only supported for AT90-based boards. This commit generalizes the code and adds support for boards based on STM32F1 and STM32F4.
- Move FWRETRACT to the planner
- Combine leveling, skew, etc. in a single modifier method
- Have kinematic and non-kinematic moves call one planner method
* Automatically reset stepper timeout in manage_inactivity
Any code that adds moves to the planner can skip resetting the stepper timeout. We can let `idle` / `manage_inactivity` reset the timer whenever it detects any moves in the planner.
* blocks_queued => has_blocks_queued
- Watchdog reset during SD Card initialization.
- Move `DebugMonitor` to `DebugMonitor_Due.cpp`.
- Since the watchdog is enabled on boot do extra resets during init.
- Have `thermalManager` do watchdog reset before its ISR starts to prevent reset.
- Ensure that timers are stopped before reprogramming them to address tone issues.
- Improve SAM3XE reset when reflashed through the native port.
