Rewrote the Depth Camera Shader by Shader Graph to better support URP/HDRP. And added documents for migration.
The depth value of the depth camera means the perpendicular distance from the camera plane, not a straight line from the object to the camera lens. So it is corrected.
Changed asmdef to exclude Editor scripts when building.
Load the shader via a material reference and create the corresponding material. This means there is no longer need to add custom shaders to the Always Included Shaders when building.
