Add pilight dimmer as light component

[Trekky12]

Description:

I would like to make a new attempt to add the pilight dimmer as light component.
I refactored the pilight switch so that there should no duplicated code.

The event bus is still used for device communication to not break an existing feature (see #7344 and #7372).

Example entry for configuration.yaml (if applicable):

light:
  - platform: pilight
    lights:
      test2:
        on_code:
          protocol: kaku_dimmer
          id: 23298822
          unit: 10
          'on': 1
        off_code:
          protocol: kaku_dimmer
          id: 23298822
          unit: 10
          'off': 1
        on_code_receive:
          protocol: kaku_dimmer
          id: 23298822
          unit: 10
          state: 'on'
        off_code_receive:
          protocol: kaku_dimmer
          id: 23298822
          unit: 10
          state: 'off'

Could someone give me some hints how to fix the CI errors?

@Trekky12 sure thing, you can take a look at the individual errors by clicking on Details and then navigating to Azure DevOps. In your particular case I would suggest you read the development checklist which should help you solve the formatting and linting error.
