libsysprof-gtk: add snapshot_motion to chart layer

Browse Source 
This allows snapshoting the motion highlight separate from the rest of the
layer so that we can have better render tree diffs. Otherwise we risk
having to snapshot a large dataset from the chart layer itself rather than
just the hightlight areas that changed.
