Adding a new Camera Server implementation to Godot. This is a new singleton where camera sources such as webcams or cameras on a mobile phone can register themselves with the Server. Other parts of Godot can interact with this to obtain images from the camera as textures. This work includes additions to the Visual Server to use this functionality to present the camera image in the background. This is specifically targetted at AR applications.

#include "camera_feed.h"
Texture refactor -Texture renamed to Texture2D -TextureLayered as base now inherits 2Darray, cubemap and cubemap array -Removed all references to flags in textures (they will go in the shader) -Texture3D gone for now (will come back later done properly) -Create base rasterizer for RenderDevice, RasterizerRD
