Move Process_PointerCapture to CursorInputMapper_test

This test will now be using the new test infra set up in
CursorInputMapper_test instead of the one in InputReader_test.

This specific test documents the behaviour of pointer capture - the
generation of ACTION_MOVE events during pointer capture, and the use of
SOURCE_MOUSE_RELATIVE.
