Feat/black voodoo magic swift voidptr

[mrousavy]

Rewrites the whole Swift HybridObject factory part to be a static class that receives this as a void* argument, keeping the entire Swift class unknown on the C++ side.

This hides the Swift inheritance from C++, so that we can inherit from any class and still use it in C++. Previously, if we inherit from a class that was imported from an external module, the build would fail because the external class could not be found (-Swift.h didn't import it).

Problem

This makes Nitro almost 70% slower. In Benchmarks:

• Before: 10ms
• After: 17ms
