Please close this PR. Qt6 will not be supported by the normal scripts but by a port-script instead which gets installed by qtbase

there is nothing stopping ports to be ported to vcpkg_qmake_configure when that machinery is ready. In the meantime, if the fixes just work, why not?

because it does not fix the issue that the toolchain is not forwarded.
If something does not work I am typically the person who gets cced?
Qt6 is currently rather clean and I don't want to introduce any hacks which this is.

try to use #20963 instead
