Kevin O'Connor 4f710b0470 avrsim: Support pacing the simulation
Support timing the simulation scaled to the system clock.  This can be
used to make the host estimation of the mcu clock more accurate.

Kevin O'Connor 5f29787dc7 avrsim: Do IO directly from simulavr callbacks
Don't start/stop the simulavr simulation loop to do IO - instead
implement the IO directly in the serial callback handlers.  This
improves the speed and consistency of the simulation.

Kevin O'Connor ab1eb70d1c toolhead: Rework lookahead flush to be more stable during high cpu
Change the lookahead queue so that it attempts to buffer at least
buffer_time_high amount of moves when first starting a print.  This
helps ensure the buffer is normally always full.

If the buffer falls below buffer_time_low then it is either due to the
end of a print or because octoprint/klippy is unable to keep up.
Change the code so that in this case the lookahead queue will attempt
to gather buffer_time_high amount of moves before restarting movement.

Update the default buffer_time_low to 1 second and buffer_time_high to
2 seconds.  With the above changes a smaller buffer_time_high and a
larger buffer_time_low are more practical.

Kevin O'Connor fe95ea221b build: Define DECL_CONSTANT mechanism for defining exported constants
Add a DECL_CONSTANT macro to allow the firmware to define constants
that are to be exported to the host during the "identify" phase.  This
replaces the existing hardcoded mechanism of scanning the Kconfig
header file for certain constants.
