Move most of the pointer manual tests to a new pointerhandlers example

They were always meant to be examples eventually. Now they will be used
for an example of how to implement custom controls using only basic
items and handlers. Some components are very similar to those in
the shared directory; but most examples will use Qt Quick Controls,
so those shared components can be removed when we no longer use them.
This example should remain as the one that shows how to build
reusable controls "from scratch".

Removed InputInspector because it's inefficient, has limited usefulness,
tends to require building the manual test to be able to run it, and
could be better built as a reusable Qt.labs component later on,
providing a model with all known devices and taking advantage of the
QPointingDevice::grabChanged signal to track the grab states rather
than polling.
