Joerg Bornemann 7be143f438 CMake: Fix default install prefix of top-level non-developer builds
A top-level non-developer build is supposed to default to a prefix like
"/usr/local/Qt-6.3.0".  That wasn't the case.

In QtSetup.cmake we check CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT,
set CMAKE_INSTALL_PREFIX and did the same thing later in
QtBuildInternalsExtra.cmake, with a different value.  Make sure we run
the latter code only in per-repo builds.

Pick-to: 6.2
Fixes: QTBUG-98087
