Fix generate combinations (#757)

* fix generate_combinations issue with Linux Qt 6.7

Qt 6.7.0 changes the default arch for Linux from gcc_64 to linux_gcc_64.
This allows the generate_combinations.py script to account for that.

Also, Qt 6.7.0 is missing a few architectures that were present in
earlier versions of Qt6. This makes sure that the script can pick those
up.

* black (v 24.1.1)

New version of black formats metadata.py differently than before

* Fix broken generate_combinations.py script

Versions 6.5 and 6.2 must be complete versions

Don't try to fetch Qt6 for target==winrt; it doesn't exist
