Issue description

Paged Allocator that's part of the core templates isn't exposed to GDExtension.
/core/templates/paged_allocator.h

Steps to reproduce

With the 4.5 branch of Godot-CPP repository, try including templates/paged_allocator.hpp and compile your GDExtension

Minimal reproduction project

A GDExtension project simply trying to include the PagedAllocator should be more than enough to repro this issue.

[Naros]

You cannot include a godot engine header file in godot-cpp, that's not supported. The only files you should be including when creating a GDExtension are the headers that are part of the godot-cpp repository or that are auto-generated by the bindings script.

[Ivorforce]

Sure, but we can make a PR to add paged_allocator.h to godot-cpp. All (I think) core templates are in scope to be added to godot-cpp.
