ui: Make PointerDetails a struct

This allows the updating of the members directly which will allow the
propagation of pointer type for on-screen stylus devices and also
permit the removal of TouchEvent::set_radius_x/y and
MouseEvent::set_pointer_details. For reviewability this CL only contains
the migration from class to struct and the switch from accessors to
direct member access. A follow-up CL with contain the refactoring.

The special case of using non-zero radius if the other is not present is
now handled in the constructor. This is tested with the existing tests
in event_unittests.

BUG=519337, 575162
TEST=Everything compiles and events_unittests passes.
