Automatically install repo specific cmake find modules

Browse Source 
Some qt modules need to find 3rd party packages for which there
are no Config files. We need to write custom CMake Find modules to
find those packages. These find modules need to be installed so that
they are used when a user consumes the Qt packages.

Automatically include and install these find modules if they exist,
as part of qt_build_repo_end().
