feat(scope): Download ADB automatically on the first run

[maverick74]

Describe the feature you want

I don't know if this is possible but i think it would be useful - specially for non-techies - if:

• After installing UAD, on the first run, it would automatically download and install/extract ADB.

This would simplify all the process to get UAD working and reduce it to a kind of "one installation process and you're ready to go"!

To a user the experience would be something like:

1. Install UAD,
2. connect the phone to PC and
3. remove the apps you want

(don't know if this is possible, however... just an idea ;). Feel free to close it as nonsense if it feels like it! )

An alternative to this is to embed ADB within UAD-ng itself. There are 2 main ways to do so:

• Distrib as AppImage (Considering other distribution methods #577)
• Adding this Crate (Ditch ADB for custom Rust implementation #643)

I'd prefer using the crate, as it would allow:

• us to choose an exact ADB version (more stable and predictable than an auto-updatable ADB)
• the compiler to further optimize and shrink the sizes of UAD+ADB

* AppImage ([Considering other distribution methods #577](https://github.com/Universal-Debloater-Alliance/universal-android-debloater-next-generation/discussions/577))

Considering Linux I, personally, would prefer AppImage!
