Added a protocol screen

[26140070-cpu]

This PR adds an Protocol and Client Brand Spoofing system. It allows users to dynamically alter how the client identifies itself to Minecraft servers through a new visual interface accessible directly from the multiplayer menu. Features On-the-fly customization of the version name, protocol number, and resource pack version (Pack Version) assigned internally by the client. Developer Notes and Future Improvements Compatibility Note: A visual warning was added to the menu because servers utilizing ViaVersion or rigid network-translation proxies might experience packet de-syncs if the spoofed protocol severely mismatches the real client codebase capabilities. Known UI Glitch: The multi-line informational note at the top of the protocol screen occasionally clips or gets cut off depending on the window's resolution scale.

Thanks for the PR! I will test it as soon as possible.

A few things:

1. The initialization / spoofing code needs a little bit of polish. The initialization and spoofing logic should be moved to a new class (ProtocolManager) so that the responsibility is not split between the Aoba and ProtocolScreen classes. This will make it easier to debug, unit test, and audit.
2. In the reflection code, we should clean up the long namespaces if possible (net.minecraft.WorldVersion for example can just be imported and reduced to WorldVersion).
3. Is it possible to replace reflection with a Mixin approach instead? It may be a better solution if we can confirm that these variables are accessed through a getter, which we can inject into.

@ModifyConstant(method = "protocolVersion()I", constant = @Constant(intValue = 4))
private int injected(int value) {
  return NEW_VERSION;
}

OR

@Mixin(SharedConstants.class)
public class SharedConstantsMixin {

    @Inject(method = "getCurrentVersion", at = @At("HEAD"), cancellable = true)
    private static void onCurrentVersion(CallbackInfoReturnable<WorldVersion> cir) {
        cir.setReturnValue(myCustomVersion);
    }
}

Thanks for the feedback I'll gonna do that rn. When I finish ill send the commit

I add the protocol manager natives Mixins to get the package and the brand added new font cause looks sooo tuff, return Aoba.java how it was before and added to more loaders (quilt, NeoForge and liteloader)
