QtPlatformSupport: A helper library for platform plugins

QtPlatformSupport is a static library. Platform plugins are meant to
link against this library to pull in dependencies such as fontengines
and convenience functions for finding the right GL configs. The linker
will only pull in the symbols used, so the size of the library doesn't
really matter
