EntityBase Refactor (#2418)

* Renamed Nameable to EntityBase (cpp)

* Renamed NAMEABLE_SCHEMA to ENTITY_BASE_SCHEMA (Python)

* Renamed cg.Nameable to cg.EntityBase (Python)

* Remove redundant use of CONF_NAME from esp32_touch

* Remove redundant use of CONF_NAME from mcp3008

* Updated test

* Moved EntityBase from Component.h and Component.cpp

* Added icon property to EntityBase

* Added CONF_ICON to ENTITY_BASE_SCHEMA and added setup_entity function to cpp_helpers

* Added MQTT component getters for icon and disabled_by_default

* Lint

* Removed icon field from MQTT components

* Code generation now uses setup_entity to setENTITY_BASE_SCHEMA fields

* Removed unused import

* Added cstdint include

* Optimisation: don't set icon if it is empty

* Remove icon from NumberTraits and SelectTraits

* Removed unused import

* Integration and Total Daily Energy sensors now inherit icons from their parents during code generation

* Minor comment correction

* Removed redundant icon-handling code from sensor, switch, and text_sensor

* Update esphome/components/tsl2591/tsl2591.h
