Fix T66452: Convert Curve to Grease Pencil Strokes

This commit adds support to convert curves to Grease Pencil strokes and create the materials too.

Also, there is a new python API. This API is required by the modified SVG import addon to create strokes( see T67065).

All curves selected in one operation are converted in the same Grease Pencil object.
