Enable deferred parallel batch compilation for image renders. This replaces the use of the `WM_job` system with a regular thread, since `WM_job` requires access to the main context, which is not accessible from the render thread. It also simplifies the system so it creates a single thread at startup and deletes it at exit. Pull Request: https://projects.blender.org/blender/blender/pulls/125005
