charts: add CN1SS:DBG enter/bounds/exit logging in XYChart.draw

The CN1SS:DBG:ChartComponent.paint output from commit 36137d1 showed
chart-line on iOS GL gets a 38ms first paint at gxT=825 then two 3ms
post-transition paints at gxT=0, with no exception bubbling up. Round
charts on the same harness pattern paint correctly. Adding entry,
bounds (left/top/right/legendSize) and exit logging inside
XYChart.draw narrows down whether the iOS XY chart paint is actually
running through the full draw or bailing inside one of the early
checks.
