Add support to attach generic extensions on job submission. This patch is third prep work to enable multiple syncobjs on job submission. With this work, when the job submission interface needs to be extended to accommodate a new feature, we will use a generic extension struct where an id determines the data type to be pointed. The first application is to enable multiples in/out syncobj (next patch), but the base is already done for future features. Therefore, to attach a new feature, a specific extension struct should subclass drm_v3d_extension and update the list of extensions in a job submission. v2: - remove redundant elements to subclass struct (Daniel) v3: - add comment for v3d_get_extensions
