OmarSquircleArt 8cd0da88e5 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.
