Adding support for commonly found SR223 solar controller (#4722)

* Adding support for commonly found SR223 solar controller

* Update sr223_solar_controller.yaml

Updated to support new config syntax

* fix (shuangri_sr223_solarcontroller): naming changes

- add manufacturer (likely original manufacturer based on online manual availability and match to model prefix)
- follow file naming convention brand_model_type
- Use generic top level name in case of other models matching
- follow HA naming convention (only first word capitalised)
- shorten entity names
- use HA provided class translations for signal_strength
- add unit to pump speed
