CMake: Propagate qtbase's CMAKE_STAGING_PREFIX to Qt modules

Browse Source 
When qtbase is configured with CMAKE_STAGING_PREFIX set, then Qt modules
built against this qtbase should also get CMAKE_STAGING_PREFIX by
default.  Like CMAKE_INSTALL_PREFIX in regular builds, this prefix will
be determined by the location of QtBuildInternalsExtra.cmake to support
building Qt modules against an installer-provided Qt.

CMAKE_INSTALL_PREFIX on the other hand must be exactly the value that
was provided when building qtbase.

If CMAKE_STAGING_PREFIX is specified by the user, honor it.

To opt out of automatically setting CMAKE_STAGING_PREFIX, set
QT_BUILD_INTERNALS_NO_FORCE_SET_STAGING_PREFIX to ON.

Remove the old code that was supposed to set CMAKE_STAGING_PREFIX.
