* Initial orjson support take 2 Still need to work out problem building wheels -- Redux of #72754 / #32153 Now possible since the following is solved: ijl/orjson#220 (comment) This implements orjson where we use our default encoder. This does not implement orjson where `ExtendedJSONEncoder` is used as these areas tend to be called far less frequently. If its desired, this could be done in a followup, but it seemed like a case of diminishing returns (except maybe for large diagnostics files, or traces, but those are not expected to be downloaded frequently). Areas where this makes a perceptible difference: - Anything that subscribes to entities (Initial subscribe_entities payload) - Initial download of registries on first connection / restore - History queries - Saving states to the database - Large logbook queries - Anything that subscribes to events (appdaemon) Cavets: orjson supports serializing dataclasses natively (and much faster) which eliminates the need to implement `as_dict` in many places when the data is already in a dataclass. This works well as long as all the data in the dataclass can also be serialized. I audited all places where we have an `as_dict` for a dataclass and found only backups needs to be adjusted (support for `Path` needed to be added for backups). I was a little bit worried about `SensorExtraStoredData` with `Decimal` but it all seems to work out from since it converts it before it gets to the json encoding cc @dgomes If it turns out to be a problem we can disable this with option |= [orjson.OPT_PASSTHROUGH_DATACLASS](https://github.com/ijl/orjson#opt_passthrough_dataclass) and it will fallback to `as_dict` Its quite impressive for history queries <img width="1271" alt="Screen_Shot_2022-05-30_at_23_46_30" src="https://user-images.githubusercontent.com/663432/171145699-661ad9db-d91d-4b2d-9c1a-9d7866c03a73.png"> * use for views as well * handle UnicodeEncodeError * tweak * DRY * DRY * not needed * fix tests * Update tests/components/http/test_view.py * Update tests/components/http/test_view.py * black * templates
