[PM-11691] Remove Nord and Solarized Dark from extension (#11013)

* remove nord and solarized dark from AppearanceV2 component
- This component already behind the extension refresh feature flag

* update the users theme to system when nord or solarized dark is selected

* For desktop, still allow all theme types by overriding the default theme service.

* change theme on the fly rather than updating local state.

- When the feature flag is removed then a migration will have to take place
