Add a new LCD_MESSAGE_INFO priority which can be overridden by regular
status updates, but only if a certain amount of time has passed.
Assign a time stamp to all message updates, so that the time since the
last update can be determined. Also switch the message type to Status,
so that the message always becomes visibile.
Always show status or info messages when printing via SD if the message
is recent enough.
Explicitly show which axes are affected on the status line when a crash
has been detected.
When the crash recovery prompt is triggered, also show all axes which
have been affected during the detection interval (currently X, Y, or
both).
The timer detection has been simplified to match the MK3 optical
filament timeout handling, which makes more sense: a crash immediately
following a crash recovery prompt will trigger the prompt again. The
timer needs to properly expire in order to reset the crash count.
This helps crash detection tuning (and help users reporting issues with
crash detection) without having to monitor the serial line.
This currently abuses the MSG_CRASH_DETECTED message by prepending the
[X][Y] labels to the message, which is ok in english but might not
translate that well for all languages.
