Issue description

There is a mismatch between the name of the utility functions struct/class in core vs in godot-cpp.

struct VariantUtilityFunctions {
	// Math

In godot-cpp:

namespace godot {

class UtilityFunctions {
public:

We should rename one or the other to allow C++ code to work for both.

In the meantime, it's easy to work around: https://github.com/godot-dimensions/godot-4d/commit/b28c83d2608191e8187703efbbeeee16365975e4
