Custom NativeLibraryLoader Implementation about sdevlibs

The public API will be managed, minus theSafeHandles to store the void* pointer for handles. Everything unmanaged and unsafe will be private, allowing for minimal confusion.

I am also leveraging the new CodeGenerators in C# to allow for a DllImport-like attribute to auto-generate the unmanaged delegates and managed wrappers for each method.

Consider separating the unmanaged api from the managed one.
A lot of people go the unmanaged route because its more optimized,
but then its more difficult to use and requires compiling with unsafe.

I'd like to pooint out that this part is not going to be imediate, as I already have enough of a headache at the moment. Everything unmanaged will remain private for the most part, though.

Eventually, as a note to self, I need to look more into nuint and related structures.

Now, while it will build, there is no UI functionallity, just the base classes and a few of the raw bindings. If you look at Libui.cs in the feature branch, you can see what the real difference the code generator will make in the future. Right now, the bindings are confusing to write,and read.
