GPencil: New python API to force stroke triangulation data update 

In some python scripts, the coordinates of the points are manipulated, but there are no way to force the recalculation and need hack to force the refresh.

The new api allows to call to the refresh function directly.

example: `gp_stroke.points.update()`
