SDL3 upgrade

[Berstanio]

This PR removes the jampad dependency and uses the lwjgl3 SDL bindings instead.
Some classes from jampad have been moved over. I didn't saw the need for jampad being a seperate project anymore, as lwjgl3 provides the bindings now.
This PR depends on the 3.4.0-SNAPSHOT of lwjgl3.

By accident, I applied similar fixes as done in this pr: #38
This pr is based of this pr: #39

Is there a problem for Lwjgl2 projects having both Lwjgl3 and 2 in the classpath?

[PokeMMO]

There's a problem for lwjgl2 projects having lwjgl2 on the classpath.

But yeah, you can't have both 2 and 3, it will cause issues.

[MrStahlfelge]

Okay, I see the problem that people might not want to use Lwjgl3, but they can stick on older versions of libgdx and this library so this should not stop us.

However, I caused some conflicts by merging your other PR which I eventually tested and is needed to make the build succeed.

[MrStahlfelge]

We should raise the version to 2.3.x (and make a 2.2.4 release) and add a new entry into the compatiblity matrix pointing out incompatibility with lwjgl2 projects.

[MrStahlfelge]

Is the snapshot version needed? Not good to have this library point to a snapshot

[Berstanio]

For the moment yes, so I would only merge this after a stable lwjgl3 release exists.

Probably 'test/desktop' can be removed - it should not work any more?

'test/ios' does not compile, it seems like there is a dependency problem. Probably RoboVM needs to get updated to the version 1.13.x uses

Yes, removed it.

A class was apparantly moved, fixed the import. I also upgraded roboVM in one go
