Add QQuickTest::pointerPress/Move/Release convenience functions

More autotests should test mouse, especially touch and maybe tablet
events, with similar expectations, instead of testing mainly mouse and
mostly neglecting the other device types. This makes it easier to work
with data-driven tests that take specific QPointingDevice instances as
test data.

Started using them in tst_TapHandler::gesturePolicyDragWithinBounds()
which was already data-driven by device type. Clearly, this code is
now easier to read and less repetitious.

In tst_qquickwindow::subclassWithPointerEventVirtualOverrides() the
improvement is somewhat smaller, but this test validates that
tablet events are working.
