Can you also remove the multiprocess import now?

Bit surprised that you can import both pyqt and pyside in one process.

#10885 needs to be merged too before removing multiprocessing (or I can rebase the later of the two PRs).
I think the impossibility of importing qt4 and qt5 in the same process is due to C symbol clash(?), so that's not a problem with pyqt and pyside(?).

This will basically become obsolete once #11600 or a variant thereof gets merged (we won't be checking for the GUI toolkits during the build at all anymore).
I guess #11600 (or variant) should get in soon so I'll remilestone this away from 3.0 for now; I'll close this once #11600 goes in (it's not a problem either if this gets merged if #11600 ends up taking too long).
