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.

Materials: support true float4 attributes in the Attribute node. Add a new Alpha socket to the Attribute node that outputs the fourth component of the attribute. Currently the only such attribute is vertex color, but there may be more in the future. If the attribute has no alpha channel, the expected value is 1. The Cycles code is already refactored and committed by Brecht. Ref D2057 2020-08-04 17:56:39 +03:00			`outcol = vec4(attr.xyz, 1.0);`
