Remove QtViewer remnants

Per aothms's request on #8605: QtViewer is being superseded by the new
Bonsai Viewer, so its remains are deleted here (src/qtviewer, its
BUILD_QTVIEWER cmake option and add_subdirectory, and its references in
ci.yml's path filter, .gitignore, the conda recipe's license table, and
README's library table).

src/ifcopenshell-python/ifcopenshell/geom/app.py's qtViewer3d is
unrelated (pythonocc-core's own OCC.Display widget class, a name
coincidence) and is untouched.

Generated with the assistance of an AI coding tool.
