media-gfx/freecad: add 0.20.2

- cleanup some depstrings (med, vtk, boost)
- not yet ready for py311 (SEGV when running test suite)
- backport changes from live ebuild to prepare for Qt6 (headless -> gui USE flag)

+# To get required dependencies:

+# We set the following requirements by default:
+# arch, draft, drawing, import, mesh, part, qt5, sketcher, spreadsheet, start, web.
+#
+# Additionally, we auto-enable mesh_part, flat_mesh and smesh
+# Fem actually needs smesh, but as long as we don't have a smesh package, we enable
+# smesh through the mesh USE flag. Note however, the fem<-smesh dependency isn't
+# reflected by the REQUIRES_MODS macro, but at
+# cMake/FreeCAD_Helpers/InitializeFreeCADBuildOptions.cmake:187.
+#
+# The increase in auto-enabled workbenches is due to their need in parts of the
+# test suite when compiled with a minimal set of USE flags.
