testlib: start sharing common helper functions

... by moving them in QTestPrivate namespace (qtesthelpers_p.h). This
header file is a convenient staging area for helper APIs, eventually
some could be moved to public QTest API.

This header file utilizes the same pattern as other qtestlib header
files - wrapping functions with QT_${LIBNAME}_LIB to automatically
enable certain APIs based on what is in the projects dependencies,
e.g. QT += widgets.
