Bug#1057346: qt6-base-dev-tools is wrongly marked Multi-Arch: foreign

I also had some talk with Sandro about this and this got me started on a
patch (attached). Once we have the wrapper, the next and more
significant question arises where to put it.
There are two basic requirements:
1. The qtconf cross wrapper must end up in some package that is marked
Multi-Arch: same.
2. The package(s) that others depend on when they expect a working
qtconf must be marked Multi-Arch: same.
At this time qtconf is installed to qt6-base-dev-tools and that is
marked Multi-Arch: foreign (violating 1). Despite qt6-base-dev-tools
saying that you should not depend on it, 22 packages do just that.
Presumably they do it for using qtpaths (violating 2). There is also
four binary packages that depend on it.
I see two paths forward and we need a lasting decision on which one to
take as either of them is non-trivial effort.
A. Give up on marking qt6-base-dev-tools as an implementation detail
and agree that the present use is ok. As a result, the package must
be split and we get practically rename qt6-base-dev-tools into
qt6-base-dev-tools-bin and then add a new qt6-base-dev-tools that
ends up being Arch:any + M-A:same + D:qt6-base-dev-tools-bin and
it contains very little beyond /usr/bin/<triplet>-qtpaths6. Also
bear in mind that since the qt6.conf resides in the qmake6 binary
package, the new qt6-base-dev-tools must also D:qmake6 enlarging it
installation set in non-trivial ways. Alternatively, qt6.conf must
be moved to yet another M-A:same package that is more fundamental.
B. Double down on qt6-base-dev-tools and file rc bugs against 22
source package users and 4 binary package users asking them to move
their dependency to qt6-base-dev. Then, we can add
/usr/bin/<triplet>-qtpaths6 to qt6-base-dev and stuff will work.
Given the above, can you make a decision? Would you need any further
information?
