render3d: actor_own_skin / skin_clone_free, and a frame's scratch and tables made with the device

Browse source 
actor_own_skin(a) gives an actor its own clone of its model's skeleton and actor_release frees it
(skin_clone_free: the pose, matrices, views and scratch the clone made; the rest data stays its
source's). gvk_startup_state, at the end of gvk_init, makes the scratch and tables a draw used to
make on first need (gvk_tmp_buf, the pipeline fast cache, the set key and per-program uniform
offsets pre-sized to 4096 programs, skip/seen/size words, spare and retired lists, the grass cull's
words), and those frame paths no longer start them. Compiled (steady).
