ledcAttachPin shoud support output_invert param (IDFGH-8781)

[dkwach]

Is your feature request related to a problem?

We can imagine that device controlled by ledc driver is connected by NPN or PNP transistor.
It would be perfect to have output inversion, which already is supported by ledc_channel_config called from ledcAttachPin

Describe the solution you'd like.

Extend ledcAttachPin interface to support output_invert

  void ledcAttachPin(uint8_t pin, uint8_t chan, uint8_t output_invert)

Describe alternatives you've considered.

IDF already has output_invert member in ledc_channel_config_t (docs).

It looks like you are referring to ledcAttachPin function defined in the arduino-esp32 project here, so I'll move this feature request over to arduino-esp32.
