The draw-distance cull for attached external weapon models checked
MR_ATTACHED_MODEL, but nothing has set that flag since commit
1ef7688fa1, so $Weapon Model Draw Distance: has been dead for years.
The check also needed the ship resolved from the render params' object
number, which is deliberately not set while weapon models render
(setting it would make model_render_queue clobber the explicitly
passed gatling model instance), and it compared against a depth
computed as if the weapon model's ship-local position were in world
space.
Carry the distance in model_render_params instead
(set_attached_model_draw_distance, negative = not an attached model),
set by ship_render_weapon_models from the ship's tabled value. When
set, model_render_queue measures depth from the eye position expressed
in the parent's frame (model_draw_list::get_view_position), which is
correct under the pushed parent transform, culls against the tabled
distance, and uses that same corrected depth for detail level
selection -- previously attached weapon models picked their LOD from a
garbage depth (roughly the eye's distance from the world origin).
MR_ATTACHED_MODEL is removed; nothing else referenced it. The unused
flags are also removed and the remaining flags are consolidated.
