[bme68x_bsec2_i2c] BME68X Temperature+Pressure+Humidity+Gas Sensor via BSEC2 (#4585)

* Added initial bme68x component

* Initialize all child sensors to nullptr

This was added to all other sensors in #3808

* Update BSEC2 and BME68x Libraries

Current versions from Bosch Sensortec

* Add myself to codeowners for bme68x_bsec

* Move constants to const.py, according to ci-custom checks

Move constants to const.py, according to ci-custom checks

* Update library dependencies

We'll stick with 1.4.2200 for now. 1.4.2200 is not on platform.io registry, use tag instead.

Update to 1.5.2400 needs some work due to multi instance support.

* Update BSEC2 to 1.6.2400

* Add consts to bme680x_bsec

Enable inclusion with external_components

* Update device class for pressure

* Update to use multisensor API

* Tidy up some constants

* Add tests

* Remove scd30 changes

* Import CONF_SAMPLE_RATE

* Pull BSEC config blob from repo based on config

* Rename component to `bme68x_bsec_i2c`

* Fix tests + codeowners

* Cleanup for review

* Rename using `bsec2`

* Apply suggestions from code review

* Download file during validation stage, instead

* Make `dump_config()` only dump stuff

* Compile safely without sensor and text sensor headers

* Use `intf_ptr`

* Save state if measuring static IAQ, too

* Update CODEOWNERS

* Simplify esphome/components/bme68x_bsec2_i2c/__init__.py

* Remove extraneous colon & imports

* Track & save the maximum accuracy value

* Polish up accuracy sensor handling

* Log static sensor, update `defines.h`

* Walruses make it better

* Add some logging of setup failures

* Update esphome/components/bme68x_bsec2_i2c/bme68x_bsec2_i2c.cpp

Co-authored-by: Trevor North <trevor@freedisc.co.uk>

* Break out some things

* Update CODEOWNERS

* Update CODEOWNERS take 2

* Use `add_extra` in base schema

* Another walrus in the sensor
