Revert "Forward touchEvents to children inside QGraphicsProxyWidget"

This reverts commit 1ecf2212fae176b78c9951a37df9e33eb24d4f2d.

The fix is not correct after all. TouchBegin goes to the correct
widget with the fix, but following TouchUpdate and TouchEnd events
now go to the viewport, as QApplication::translateRawTouchEvent always
gives precedence to the widget that Qt recorded to be the touch
grabber, which is the viewport. This results in infinite recursion,
as the proxy widget trying to send the touch events to the embedded
widget (expecting that translateRawTouchEvent will split it up) ends
up sending the events back to the viewport.

Leave the added test case as QEXPECT_FAIL, reactivate the (never run,
hence unnoticed) test that the fix broke.
