feat(bundler): bundle additional gstreamer files, closes #4092

[FabianLars]

A couple of things:

1. i know it's weird to have a new appimage config like this, a more obvious choice would be to have a new "parent" linux config for both appimage and deb (especially for consistency between OSes). I'm happy with changing it, i just didn't want to start this PR with a breaking change.
2. idk how to call the flag, so i just went with gstreamer for now.
3. It currently should fail to build on non ubuntu-like systems because i didn't modify the gstreamer plugin yet, but since this is not bound to tauri's release pipeline i thought it be better to at least get the PR out asap.
4. The fix that worked ~3 weeks ago doesn't really work anymore. It still fixes app crashes but it doesn't play videos on youtube and twitch (some other pages like https://camendesign.com/code/video_for_everybody/test.html work fine tho), it could very well be my system's fault because it's acting up generally right now. I'll do some VM testing when i make changes to the plugin (tomorrow)
5. As of now the plugin re-introduces the patchelf dependency and i'm not 100% sure if we will/can get rid of it (didn't really look at it).

1. I don't think it's weird to have an AppImage config tbh.
2. the flag could name could be bundleMediaFramework or something like that, gstreamer doesn't seem that bad too - i also hate naming things

[FabianLars]

1 Yeah i'm happy with an appimage config too, it's just that i keep comparing it to windows > wix in my head. And then i think about potential rpm and flatpak props too. Well we can worry about that for v2 i guess 🤷

2 i like bundleMediaFramework, should be clearer for non-linux people etc. Unless we want to keep it synced with the env var because i'd prefer that to still be called something with gstreamer

[lucasfernog]

Yeah let's worry about reorganizing the config options in v2. And we don't need to sync with the env var, makes more sense to keep using gstreamer since the bundler is also used by non-tauri users.

@FabianLars is this one ready to be merged or do you want to change something?

[FabianLars]

This PR won't receive any more changes, only the plugin itself will, to make it work on more distros (and hopefully fix the youtube&twitch issue again)
