Fix configuration version conflict between the Qt 5 and Qt 6 AM
The configuration caches are versioned, but the Qt 5 and 6 versions
got their cache version numbers bumped independently.
This led to a situation where 5.15.12 and 6.4.2 both ended up at
version '9', although they are binary incompatible.
The fix here is to encode the major Qt version into the cache header
as well, to make caches incompatible between Qt major versions.
Change-Id: I7bbf7cb97cc1ea8bc4f16285588958ba11c19833
Pick-to: 6.2 6.4 6.5 6.5.0
