The gcode.run_script() code can pause which can result in the menu
code being called reentrant - avoid that by queuing the gcode commands
within the menu code.

Don't pass pin_type to lookup_pin() - instead, if a pin can be
inverted or can have a pullup, then the caller must explicitly specify
that when calling lookup_pin(). This simplifies the code for the
cases where it is not valid to invert or pullup.
Explicitly pass the pin_type to setup_pin() and have ppins.setup_pin()
apply default pullup and invert flags.

Don't issue a get_config command after building the config as the
built config may contain time sensitive initialization commands.
Instead, send the config and init commands immediately after invoking
the build_config() callbacks. This avoids some rare "timer too close"
errors during configuration.

Switch the host code from the CLOCK_MONOTONIC clock to the Linux
specific CLOCK_MONOTONIC_RAW clock. It's common for ntp to slew the
CLOCK_MONOTONIC clock to account for drift, and that can break the
host's ability to make accurate predictions of the micro-controller
clock. This could lead to "move queue empty" errors. The
CLOCK_MONOTONIC_RAW clock is not slewed and thus should not have this
problem.

Add generic temperature smoothing to the Heater class. This is useful

Extend the ADC out of range check so that it is possible to sample
multiple times before going into a shutdown state. This reduces the
chance that measurement noise will cause an error. In an actual over
temperature (or under temperature event) it is expected that the
sensor will consistently report the problem, so extra checks for an
additional second or two should not substantially increase risk.

It appears the st7920 requires a longer delay when switching from
command to data mode (and vice-versa). Slower MCUs don't show a
problem because the klipper command processing time results in a
sufficient delay. However, some of the faster MCUs can process
klipper commands fast enough that the next st7920 transfer is sent too
fast. Add an additional delay to account for this.
