GPU: Split gpu_shader_material into multiple files. This patch continue the efforts to split the `gpu_shader_material` file started in D5569. Dependency resolution is now recursive. Each shading node gets its own file. Additionally, some utility files are added to be shared between files, like `math_util`, `color_util`, and `hash`. Some files are always included because they may be used in the execution function, like `world_normals`. Some glsl functions appeared to be unused, so they were removed, like `output_node`, `bits_to_01`, and `exp_blender`. Other functions have been renamed to be more general and get used as utils, like `texco_norm` which became `vector_normalize`. A lot of the opengl tests fails, but those same tests also fail in master, so this is probably unrelated to this patch.

EEVEE: Render Passes This patch adds new render passes to EEVEE. These passes include: * Emission * Diffuse Light * Diffuse Color * Glossy Light * Glossy Color * Environment * Volume Scattering * Volume Transmission * Bloom * Shadow With these passes it will be possible to use EEVEE effectively for compositing. During development we kept a close eye on how to get similar results compared to cycles render passes there are some differences that are related to how EEVEE works. For EEVEE we combined the passes to `Diffuse` and `Specular`. There are no transmittance or sss passes anymore. Cycles will be changed accordingly. Cycles volume transmittance is added to multiple surface col passes. For EEVEE we left the volume transmittance as a separate pass. Known Limitations * All materials that use alpha blending will not be rendered in the render passes. Other transparency modes are supported. * More GPU memory is required to store the render passes. When rendering a HD image with all render passes enabled at max extra 570MB GPU memory is required. Implementation Details An overview of render passes have been described in https://wiki.blender.org/wiki/Source/Render/EEVEE/RenderPasses Future Developments * In this implementation the materials are re-rendered for Diffuse/Glossy and Emission passes. We could use multi target rendering to improve the render speed. * Other passes can be added later * Don't render material based passes when only requesting AO or Shadow. * Add more passes to the system. These could include Cryptomatte, AOV's, Vector, ObjectID, MaterialID, UV.
