Library output name breaks windeployqt.exe use due to Qt6... prefix

[ThomasKroes]

windeployqt.exe sees Qt6advanceddocking.dll as a native Qt6 dll and therefore searches for it in the bin directory of the Qt distribution instead of next to the .exe. The only solution to this problem is to either:

• Copy Qt6advanceddocking.dll to the bin directory
• or rename for instance to qtadvanceddocking.dll

Steps to reproduce:

1. Create an executable with a dependency on Qt ADS
2. Compile it, this will give you an exe and a Qt6advanceddocking.dll
3. Now run windeployqt on either the exe or the dir in which it is contained
4. windeployqt will complain that it cannot find Qt6advanceddocking.dll in qt_bin_dir/Qt6advanceddocking.dll
