This adds new config options for fans: 'tachometer_pin' to specify the
GPIO pin, and 'tachometer_ppr' (default 2) to specify the number of
signal pulses per revolution. The rpm is also exposed by get_status for
command templates and the API server. For fast fans (at least 10000
RPM), the polling interval can be shortened using the
'tachometer_poll_interval' option.
There is a new mcu object for a generic edge counter, which repeatedly
polls a GPIO pin and periodically reports the count to the host.

Add mcu support for periodically polling for a button press. Add host
code support for registering buttons and invoking callbacks for them.

Allow the micro-controller code to be built without support for
regular gpio pins. In this case, the code for endstops, steppers, and
gpiocmds will be disabled.

Some boards may not support hardware based PWM. Update the build so
that those commands do not need to be compiled if they are not
available.

Some boards may not support SPI transfers. Update the build so that
those commands do not need to be compiled if they are not available.
