With the compute pipeline calculation can be offloaded to the GPU. This patch only adds the framework for compute. So no changes for users at this moment. NOTE: As this is an OpenGL4.3 feature it must always have a fallback. Use `GPU_compute_shader_support` to check if compute pipeline can be used. Check `gpu_shader_compute*` test cases for usage. This patch also adds support for shader storage buffer objects and device only vertex/index buffers. An alternative that had been discussed was adding this to the `GPUBatch`, this was eventually not chosen as it would lead to more code when used as part of a shading group. The idea is that we add an `eDRWCommandType` in the near future. Reviewed By: fclem Differential Revision: https://developer.blender.org/D10913
