GPencil: New Simplify modifier mode Sample and operator

This mode simplify the stroke doing a resampling of the points and generate new geometry at the distance defined.

Sample function developed by @NicksBest

New Resample Stroke operator

This operator recreates the stroke geometry with a predefined length between points.

The operator uses the same code used in Simplify modifier.
