This PR refactors each UI template into its own `interface_template_*.cc` file. * Added `interface_templates_intern.hh` which exposes shared utility functions and macros. * Doxygen comment sections that were redundant of the file name were removed. If they contained additional description, they were added to the file Doxygen `\file` header. * Short templates that were closely related were kept together in single files (e.g `uiTemplateHistogram`, `uiTemplateWaveform` and `uiTemplateVectorScope` are all in `interface_template_scopes.cc`). In this case, Doxygen comment section were preserved. The only things remaining in `interface_templates.cc` are: * Common utility function exposed by `interface_templates_intern.hh` * Small independent templates (`uiTemplatePathBuilder`, `uiTemplateNodeSocket` and `uiTemplateFileSelectPath`) Ref: https://projects.blender.org/blender/blender/issues/117604 Pull Request: https://projects.blender.org/blender/blender/pulls/132468
