Alexandru Croitor ffe0889413 Fix examples find_package calls to work in prefix builds
To build examples as part of a non-installed Qt prefix build,
not-yet-installed Config files need to be found by find_package()
calls inside example projects.

Facilitate that by propagating the CMAKE_PREFIX_PATH and
QT_EXAMPLES_CMAKE_PREFIX_PATH paths in all relevant find_package()
calls where NO_DEFAULT_PATH is used.

Also adjust the inclusion of the QtFeature.cmake file to be relative
to the qt6 directory, rather than the current list directory.
This is needed to successfully find the file when parsing a Config
file from a non-installed build directory.
