Add PackedRealArray as an alias for PackedFloat(32/64)Array

[aaronfranke]

This PR adds PackedRealArray as an alias for PackedFloat(32/64)Array to allow you to specify that you want an array of the float size defined for real_t. In the core engine, it is possible to use Vector<real_t>, but this is not possible in GDExtension because PackedFloat(32/64)Array are explicit types and not just Vector<T>.

I used using instead of #define to ensure that the namespace is preserved, so that if you don't have using namespace godot; then you need godot::PackedRealArray just like you would need godot::PackedFloat32Array. I also tried using typedef and it works fine too including with the namespace, but using is the newer preferred syntax.

Thanks! This makes sense to me. I would hit "approve" but I don't want this to accidentally get merged before the equivalent change is merged to Godot. :-)

Incidentally, having this upstream as a GDExtension type would also solve one of the problems with godotengine/godot#86346. (There are still others remaining).

Is this not what the waiting for Godot label is for?

Oh! I was not aware of that label. Would production team folks hold off from merging an approved PR if that label is present?

I don't know, seems so from the description, like the one in docs, just add a note in the op for the Godot side PR I'd say to help indicate

Well, I don't think the production team does much merging here, so it's mostly a signal for yourself 🙃

I know he's on vacation right now, but lately Remi's been merging approved godot-cpp PRs before I have a chance to :-)

Thanks!
