Description

This PR adds basic external player functionality for PotPlayer, MPC-HC and MPC-BE.
It also sorts the list alphabetically, because UX.

Note that MPC-HC requires yt-dlp or similar to be present.
It will also fail to properly play back videos with a startOffset if the resolution is > 1080p (audio will play, video will be black). Unfortunately the default limit (View > Options > Advanced > YDLMaxHeight) MPC-HC ships with is 1440p.
Feedback desired on whether startOffset should stay enabled given the current state.

Note that MPC-BE requires yt-dlp or similar to be present and enabled in order to parse playlists.

Note that both MPC-HC and MPC-BE require #3797 to fix playback from within playlists.

Moves entries around

Also the indent alignment is inconsistent with other entries

[trostboot]

Thanks, fixed the indents.

As for the reordering, that was intentional so the list would be alphabetical. It just makes more sense to me. Do you have any objections to that?

[PikachuEXE]

It's harder to review the diff

If we want the display order to be updated it should be done in code not in data (with limited no. of entries)

[trostboot]

Well, I've had a look around the relevant code, but I'm afraid that's above my pay grade. Until someone else feels the need to tackle that, here's the unsorted list back :)

[PikachuEXE]

Code looks fine but I will wait for #3797 to be merged first
