Alexandru Croitor 2799391703 CMake: Rework INPUT_foo vars handling when reconfiguring 
To be able to reconfigure Qt with modified feature values using the
configure script, and take into account INPUT_foo values, we need to
ignore FEATURE_foo values. But we can't always ignore FEATURE_foo
values, because users might want to toggle them by editing
CMakeCache.txt or using an IDE.

What we can do is tell CMake we are configuring via the configure
script, in which case we can mostly be sure that any passed
INPUT_foo values should have higher priority than pre-cached
FEATURE_foo values.

We also need to remove all the cached INPUT_foo variables after they
have been used for feature computation, so that subsequent
reconfigurations where an INPUT_foo is not passed anymore, doesn't
cause a feature to accidentally reuse the previous (stale) value.

Pass -DQT_INTERNAL_CALLED_FROM_CONFIGURE=TRUE to CMake when configuring
via the configure script, and use that as a marker to make INPUT_foo
values have a higher priority.
This needs to be done centrally in qt_evaluate_feature and also in a
few more locations where we check INPUT_ values, like the developer
build and pkgconfig features.

Because QT_INTERNAL_CALLED_FROM_CONFIGURE would become a cached
variable, we want to remove it at the end of the configuration phase,
so that future 'cmake .' reconfigurations are not considered to be done
via configure.
To do that, we unset it right at the end of
qt_build_repo_end in a per-repo build, and in the final
qt_print_build_instructions call in a top-level build.
The latter needs a cleaner fix in follow up commits in qt5.git and
qtbase.
