layer.create: the instance3d op - a 2D copy of a 3D model layer (#2100)

Browse Source 
Layer > Create > Create 3D Layer Instance, as After Effects (public docs):
3D model layers take no masks or effects, so the command puts a comp-sized
solid at the top of the layer stack with CC Composite referencing the
selected model, and switches the model off (back on to keep its shadow) -
a 2D copy of its render, through the comp's camera, that 2D effects can be
applied to.

- CC Composite (ec.channel.cccomposite) gains an optional Layer parameter:
  with a layer chosen it takes the original's place; In Front replaces the
  solid's pixels, alpha included, the other Composite Original modes blend
  with them. The GPU compositor runs such an instance on the CPU.
- FxHost serves a referenced model or primitive layer as After Effects
  does - the layer rendered on its own through the comp's camera
  (Renderer::solo_3d); the owner keeps no cache entry for it (it moves with
  the camera and lights, without a trace in its own properties).
- layer.create {op: instance3d} skips layers that are not 3D model or
  primitive layers (the ones that take no effects); one undo step, the copy
  selected, the model's video off.

Tests: tests_instance3d.rs (behaviour, pixels, undo/redo, serde, 2D effects
on the copy), a CC Composite layer-parameter unit test; docs/effects.md
regenerated (3033 parameters).

EffectCraft ships 307 effects with 3032 parameters in total, grouped into the same categories as the Effects & Presets panel. Every effect is our own implementation, written from public behaviour descriptions and standard image-processing literature. Parameter names, order, popup options, units, defaults and ranges follow the reference application so that projects, expressions and muscle memory carry over.

- **GPU**: 280 effects also run on the GPU compositor with identical results.
- **32**: 307 effects process 32-bit float (HDR, overbright) pixels without clamping.
