Multiple threads would be setting the globals `g_shader_builtin_srgb_transform` and `g_shader_builtin_srgb_is_dirty`. These are use for color management inside the builtin shaders. But the render thread could modify these values even if its shader have no use of these. The fix is to move these globals to the `gpu::Context` class. This way we remove the race condition.
