Add support for the Invidious add-on when sharing YouTube URLs

[wtimme]

Feature suggestion

YouTube URLs shared with Kore should be playable with the Invidious add-on.

Detailed Description

Shared YouTube URLs currently require for the YouTube add-on (plugin.video.youtube) to be installed in Kodi. As outlined in #947, however, there are other plugins that support the playback of YouTube videos as well, such as the Invidious add-on.

Context

The YouTube add-on plugin.video.youtube requires an API key. As a privacy-conscious user, I do not want to sign in to Google and link my viewing habits to an account. Rather, I want to watch YouTube anonymously - and Invidious is a great way to do so.

Possible Implementation

Kore's settings could have a new ListPreference (e.g. titled "YouTube add-on") that allows users to select their preferred YouTube add-on. Internally, Kore could store the add-on's ID in the preferences.

In ShareOpenActivity.toPluginUrl(), Kore would check which add-on is selected and, based on that, create the Uri specific to the add-on.

I have already tried this with hard-coded values locally, and it seems to work as expected. Adding a ListPreference would allow us to extend this to other add-ons as well.

One thing to note is that not every add-on supports queuing. The Invidious add-on, for example, does not. But for the MVP, I think it would be perfectly fine to only have the video played back.

Note: Team Kodi will consider this item however we will not make any promises if it will be included.

not every addon supports queuing

Look at Tolriq/repository.yatse.kodi#41 how queuing is done - the plugin:// url is put into playlist which is queued. Also I encountered an issue with -1 as addon_handle and made a workaround PR referenced in the same link (but not merged yet :( )
