libsysprof-gtk: add chart layer for timespan drawing

Browse Source 
This will allow us to drop the custom mark chart stuff and do this all more
generically using timeseries and charts. Long term, we'll probably want to
buy in on the expression stuff to get labels/etc as well as building the
series from another data source.
