00607a20a6 feat(ugc): the fast hidden-face method back, next to LU Toolbox's
UgcHsr::Options::method picks how hidden faces are found: toolbox (LU Toolbox's
paths, the default, unchanged) or fast, the test the UGC server used before
"hidden faces removed as LU Toolbox's Remove Hidden Faces decides them",
restored unchanged as UgcRender::VisibleFromAround: the opaque mesh rendered
from 42 directions around the model (Options::fastResolution pixels square,
1024 as before) and the triangles that show in none removed. It is much
faster, but it also removes faces seen only by bounced light (interiors,
recesses), which LU Toolbox keeps. Nothing sets it yet.

Check: the UGC tests (the fast method removes a box seen only through a
chimney, which the paths keep; its files are the same every time).

57110a7081 feat(ugc): rays behind a backend interface, with Embree as a second backend
UgcRays::Scene answers the two ray queries the UGC server makes: the nearest
hit for the hidden faces' paths (never the triangle a path leaves) and any hit
for the ambient occlusion rays. Two backends:

- builtin: the two hierarchies the queries had before, moved unchanged (each
  built the first time it is asked), so the files made are the same bytes
- embree: Embree 4 on the job's thread (a device per worker thread, no threads
  of its own, so its time counts in the CPU budget), watertight, the skipped
  triangle filtered out

UgcHsr::Options::rays and UgcRender::AoOptions::rays pick the backend; both
default to builtin, and nothing sets them yet.

Check: the UGC tests (builtin's files keep their hashes; UgcRays tests compare
embree's hits, hidden faces and occlusion with builtin's).

7c32779e89 fix(ugc): transparent bricks drawn see-through in mixed models; dUgcServer in folders by role
- The client puts a shape in its sorted, blended pass only when its
  NiMaterialProperty alpha is under 0.99999 (ShaderCommon::GetAlphaFlags
  0x0109f5a0; the NiAlphaProperty blend flag isn't read); at 1.0 it's drawn
  solid with blending off. Transparent (and transparent glitter) shapes now
  get a material with alpha 0.9999, as the S01_Alpha shapes of the game's own
  brick models (res/BrickModels/ndmade) do; opaque shapes keep 1.0. Models
  with a transparent brick change; the others are byte for byte the same.
- dUgcServer's files move into Bricks/, Model/, Render/, Formats/ and
  Processing/ (the CMakeLists says what each holds); includes are unchanged.
