Fix ZHA cover inversion handling missing attributes (#109151)

* Allow `window_covering_type` to be `None`

* Create a `window_covering_mode` attribute and simplify inversion switch

* Revert "Create a `window_covering_mode` attribute and simplify inversion switch"

This reverts commit 048d649b4dff20aff2a0baa81cfdb9c7d3ce71c6.

* check both config status and mode

* coverage
