feat: ✨ Dynamic Script Components, register_new_component binding, remove_component no longer requires ReflectComponent data

[makspll]

Summary

In order to support dynamic script components we need:

• to relax some requirements on having a ReflectComponent registration to allow component operations
• add a script component registry, which stores metadata about each dynamically registered component
• Add ScriptValue to into_script_ref and from_script_ref implementations to allow any value to be inserted into the components payload

The nice thing about this implementation is it just works with the reference system.

The current problems are that the global type cache will not reflect this script component, to fix that we'd need a mechanism for "re-computing" certain globals for scripts. This also does not allow setting a schema on these, which is handy but also footgunny

As a side effect I've also made remove_component no longer require the ReflectComponent registration

• The use of Box::leak is intentional to avoid double dropping, but it bypasses Rust's ownership management. Consider adding explicit documentation or an abstraction to ensure that this design does not inadvertently cause memory leaks in production code.

let ptr = (Box::leak(cast) as *mut ScriptComponent).cast();
