feat(ugc): settings for the ray tracer, hidden-face method and denoising

Browse Source 
New UGC settings (ugcconfig.ini and the dashboard's settings page):

- ray_backend: builtin (default), embree or hiprt (falls back to embree when
  the build or machine can't); the hidden faces' paths and the occlusion rays
- hsr_method: toolbox (default, LU Toolbox's paths) or fast (the renders from
  around the model), and hsr_fast_resolution (1024) for the fast one
- denoise: off (default) or oidn (icons; off until a build has it)

UgcProcessOptions (dCommon/UgcKeys.h) names the choices for everything that
passes them on ("embree fast oidn", any order, left out: the setting's).
UgcJobs::ApplyOptions puts a choice over the settings and MadeWith says what a
make used after fallbacks; a made model's stats.json records it (rays,
hsrMethod, denoise). UgcServer --make-model and --make-modular take the
choices after the folder and print the CPU time and what made it.

Check: the defaults make the same files as before; the settings page shows the
four settings under UGC; UgcServer --make-model model.lxfml out embree fast.
