feat: Add deep link plugin for mobile

[FabianLars]

This is not meant to be merged! It's only to discuss the changes presented here, changes that are still TODO / need to be discussed, and to track what changes are required outside of the plugin (in tauri's bundler f.e.) nvm i guess

The biggest open question is how to handle the required Manifest change. I think ideally there'd be a way to reference the consuming app inside the plugin for example via a handlebar thingy that the cli replaces if that's possible. If it isn't then i think that leaves us with 2 options:

1. The user has to modify the manifest in their gen folder

2. the cli modifies that same manifest (or some other one?) at build time, or creates a new one somewhere and merge it into it

3. is basically like 0) with less plugin-specific which may help for other plugins in the future
   -> after a small convo with lucas this sounds pretty difficult

todo list (don't have to be resolved, but talked about at least):

• Android Manifest changes
• Document how to set up assetlinks.json (short)
• Explore "stupid" deep links on Android for easier testing without having to host assetlinks.json with a debug key. -> The current idea is to register the desktop schemes on mobile in development.
• After that we can hopefully not depend on my website (not that i actually care about that)
• Replace the window.__TAURI_INVOKE__ usage with listen in the next alpha release (marked as TODO in the code)
• Consider splitting up the initial intent and last intent (marked as TODO in the code)
• Remove the other event TODOs i forgot in there - waiting for Lucas' changes to not cause any conflicts.
• Obviously the iOS part is missing (Lucas is working on it)
• Switch branch back to lucas' fork -> probably part of the incoming iOS changes
• With the iOS part we'll also need to figure out an API that makes sense on both platform (we mostly already know how it works on desktop).
• Get some feedback on the api and see what issues users have consuming them
• The 3 desktop platforms should not be added in this PR imo
• Ask the tauri-plugin-deep-link maintainer if they want to transfer the crate name to us 😂

I see we're duplicating the config for build vs runtime. We can reuse the same config in an ugly way using #[path = "src/config.rs"] mod config in the build.rs file :|

[FabianLars]

yeah, i saw that in some Stackoverflow answer but wasn't sure if we're comfortable with that. Or well, could be worse i guess, so why not

[FabianLars]

marked as ready for review so we can get it merged & released asap as discussed on discord. There are still a few things we/i should/want to look into but this PR is already large enough 👍

Related to #536 (comment), I've opened an issue in tauri-apps/governance-and-guidance#42 to discuss this further, pending a non-CrabNebula board member to weigh in on this. CC @Beanow
