Refactor Vignette.Camera

[Speykious]

This PR fixes issue #234.

The previous solution that I've implemented is simply not adding a duplicate item in the FluentDropdown, and warning about it with a console write statement.

Now, the solution is indexing the friendly names so that all options pop up.
We're now faced with a "can't open camera by index" bug.

Done :v

Now I've got another problem... It's not detecting my webcam and it says that it "can't open camera by index":

[performance] 2021-10-01 18:52:00 [verbose]: TextureAtlas initialised (1024x1024)
[runtime] 2021-10-01 18:52:01 [important]: Warning: item HD WebCam: HD WebCam
[runtime] 2021-10-01 18:52:01 [important]: already exists in this FluentDropdown. Not adding it again.

This might be relevant to the problem: opencv/opencv#19527

Welp, time to rewrite this shit

Welp, time to not rewrite this shit

I'm gonna care about the reimplementation of Vignette.Camera for Encore 1. For now, I think I can focus on the "can't open camera by index" bug. There might be a problem with Camera instances as suggested there: https://stackoverflow.com/a/61817613

I'll close this now since this will not be part of the Debut codebase, just remake what you did once we have the Stride code public :D

No no, wait! I just need to rename the pull request. I originally renamed it "Refactor Vignette.Camera" because I wanted to shift to implementing an FFmpeg version, but we still have to fix the webcam duplication and "can't open camera by index" bug. I can do it without a lot of rewrite in this PR.

Do it on another PR if that's the intent, we can't do it in this one since it's main context is replacing the backend and fixing the bugs.

That is its second context, which wasn't even really engaged in any significant modifications in the code fortunately.
