DRW: Curves: Indexbuf optimization for large numbers of curves This optimizes a few loops that become significant bottlenecks during viewport rendering of scenes with large numbers of curves. To render a curves object, Blender needs to generate a potentially very large (but trivial) index buffer. As previously implemented, this index buffer is generated in an extremely inefficient manner, with a single-threaded loop and an explicit function call per entry. The buffer then needs to be pushed onto the GPU, which is also a fairly slow task. The PR generates the index buffer directly on the GPU with compute shader.

GPU: GLSL compilation as C++ for gpu static shaders Allow compilation of shaders using C++ for linting and IDE support. Related #127983 Pull Request: https://projects.blender.org/blender/blender/pulls/128724

GPU: Split GLSL, C++ and metal shader defines This makes all the defines and boiler plate code use the generated source include system. This makes source hierarchy more understandable. Pull Request: https://projects.blender.org/blender/blender/pulls/146289

GPU: Shader: Make info files generated This is the first step of moving the create infos back inside shader sources. All info files are now treated as source files. However, they are not considered in the include tree yet. This will come in another following PR. Each shader source file now generate a `.info` file containing only the create info declarations. This renames all info files so that they do not conflict with their previous versions that were copied (non-generated). Pull Request: https://projects.blender.org/blender/blender/pulls/146676
