Adding test for the Widgets reordering.

TAPL design chagnes at https://docs.google.com/document/d/1PdJZZIn-85-UMRFGZuqj-tJgruIWcg31lZnrb34iBTY/edit?resourcekey=0-uAZuiLCDFV9YhOtLB7wQHQ

The tests consist of a board representing the widgets on
the CellLayout a position to move the main widget (m) to
and the resulting board.

iiiii    iiiii
-----    --x--
-xxx- -> -xmx-
--m--    -----
-----    -----

Move m to 2,2.

Then whe make sure the device corresponds with the resulting
board.

I had to add the event TestLogging.recordEvent(TestProtocol.SEQUENCE_MAIN, "Widgets.onLongClick");
on ItemLongClickListener because the tests where not expecting
a long press on a widget after is being place on the
workspace.

Also, I needed to add the option to drag a widget
to a specific point instead of the previous option
of only dragging to the workspace.

Fix: 231449779
Test: Run the test and make sure they pass.
