HA-switch support for climate and input_boolean entities

Based on #23509.

climate and input_boolean entities are now supported in addition to switch entities for the homeassistant-switch charger template. This allows controlling devices like heaters, thermostats and smart plugs as chargers.

Dropdown selection in UI then e.g. works as follows:

I'm not happy with polluting the switch with auto and other values. That said, sgready or sgready-boost may be the better fit here. As last resort, you can always manually configure an integration using the http plugin. I'd also be open to add a homeassistant plugin that might allow more finer-grained control over response values.
