Rename try_load_module() so that it uses consistent naming for
"printer objects". Change the function to raise an error by default
if the specified module does not exist.

The heater logic is an independent module that does not need to be
treated as part of the "core" klipper code.

No longer allow the primary extruder to be named "extruder0". This
avoids internal and external confusion between the printer objects and
config section names.

Convert all users of the printer_state("ready") handler to register a
"klippy:ready" event handler instead.

Add a set_shutdown_speed() method so that the heater_fan code does not
need to peek into the fan object's internal members.

If the fan's max power is limited by the config, then scale speed
requests between 0 and max_power. This makes more sense for typical
g-code fan speeds.

Add a PrinterHeaters class that can stores references to available
temperature sensors and stores references to instantiated heaters.
Add a extras/heater_bed.py file and delay instantiation of the
heater_bed object. This allows the heater.py module to be imported
earlier during the setup phase, and allows the PrinterHeaters class to
be available for registering sensors and heaters.

Use both load_config() and load_config_prefix() functions when
dynamically loading a module from the extras directory - if the config
section name has parameters in it then use load_config_prefix().

The print cooling fan and printer heater_fan are independent modules
that can reside in the extras directory.
