Use config_hash in MQTT and version sensor

Browse Source 
Change MQTT sw_version and version text sensor to display config_hash
instead of build_time_str. Format: "(config hash 0xXXXXXXXX)"

Version sensor with hide_timestamp=false also includes build time:
"(config hash 0xXXXXXXXX, built: YYYY-MM-DD HH:MM:SS +ZZZZ)"
