render3d: frame keeps 32 to 16 - tables and queues sized at start-up, the rest declared; birth leaks freed

The texture and framebuffer tables grow to 4096/1024 and gvk_prime's queue is made in
gvk_startup_state; gpu_unit_2d's and the actor lists' lazy starts go. @alloc_ok on layer_room (a layer
outgrowing its cap), overlay_init, gvk_read_screen, gvk_hdr_metadata (a settings change), DLSS's
gsl_struct/gsl_fn, an actor's part tables (given back by actor_release) and the pool's fallback.
Birth leaks freed: gpu_caps_probe's create structs, gpu_caps_fake's text, gvk_note's line,
gvk_layout_key's table and each key it grew from, ov_text_wrap's slices, the default sky path.
(ludic deps --births still lists freed sites: its walk does not see free().) Compiled.
