feature: Show recording devices in UI

[ViktorShapoval]

Add 2 new community settings that will allow users to see and interact with recording devices in Context menu and Flyout window.

That is very useful for users who have to switch recording device based on what playback device they are using. Example: switching between headphones with integrated microphone and earphones with separate microphone device. Switching in such cases is painful using default Windows UI so EarTrumpet can help alot here.

Changes in UI are only visible when settings toggled on. Without them UI stays as before this PR.

Screenshots with new UI are below. I'm not very satisfied with how Switch to Recording/Playback buttons look and placed so suggestions are welcome here.

Hey, I think you might want to read Contributing to EarTrumpet for your feature to merge? I actually found your feature to be really useful for me, so I'm quite looking forward for this to be included.

Hi, and thanks for the feedback. As for now, I don't have clear answer from EarTrumpet maintainers whether they agree or not to include such functionality in the project. If you don't want to wait - you can take my branch and build it with Release target yourself with free version of visual studio.

I'm not opposed to this, and like the idea of adding this as a community feature, but I'm nearing the end of a major migration to .NET 8+ and new pipelines, of which this will conflict. We also have an add-on framework in the app which would probably be better suited for this. (We currently have a private repository for some in-house unreleased add-ons and managing recording devices is one of them.)

Hmm, let me think about how we want to handle this. Standby!
