(core): move remaining misplaced files

Description

(Briefly describe what this merge request is about)

Closes #678 (closed)

• Move several services interfaces from sight::service:
  • IGrabber -> io
  • IRGBDGrabber -> io
  • ICalibration -> geometry_vision
• Rename IOperator as IFilter to match the new naming scheme and avoid synonyms
• IParametersService is renamed into IHasParameters, moved in ui_base and is no longer a service. Thus any specialized service can inherit this interface using multiple inheritances.
• Rename pchServices/pchServicesOmp into pchService/pchServiceOmp (we have used the singular everywhere for service)
• Renamed and moved sight::module::ui::dicom::SSeriesDBMerger into sight::module::ui::series::SPushSelection, since it pushes a selection (vector) of series into a SeriesDB.
• Removed duplicated module::geometry::generator::SUltrasoundMesh and moved module::geometry::generator::SNeedle into the same module than the duplicate of SUltrasoundMesh, i.e. in module::filter::mesh::generator.

How to test it?

• Run some applications where these services are used:
  • SightViewer
  • DicomXplorer
