QQuickToolTip: add non-attached show() and hide() methods

Usually there's only one global ToolTip instance providing attached
show() and hide() methods, here we add non-attached ones which would be
more flexible to meet different needs.

[ChangeLog][ToolTip] Added non-attached show() and hide() methods to
make it more flexible to meet certain requirements.
