Embedded climate (#917)

* Performance improvements

The main focus here was to reduce the number of calls between Home Assistant and ESPHome, moving logic as much as possible to TFT and ESPHome.
- Service calls moved to ESPHome (in preparation for Alarm Control Panel)
- Page change informed via event call instead of `nspanel_event` sensor (which still in use by other calls, but might be possible to remove in the future)

* Draft embedded climate

This adds an initial version of an embedded climate/thermostat (heating only for now) with support for local control even with Wi-Fi out.

* Embedded chip 3
