GPencil: Fix unreported visual problem for short strokes

When the stroke has less than 3 points, but only the fill material is enabled, the stroke is invisible and makes the shaders to remove any fill because the shader start and end pointers are not correct.

Now, if the stroke has only fill, but it is not fillable, it is drawn with the stroke color to avoid the errors and these ghost strokes.

Fix T71260: GPencil crash when drawing very long lines

There were two problems:

1) When the buffer was reallocate, the pointer was corrupted.
2) Short variables were too small to hold long lines.

GPencil: Show selection in Stroke mode for single points

Gpencil: Don't use checkbox for stroke duplication modifier.

Merge remote-tracking branch 'origin/master' into temp-npr-gpencil-modifiers

Gpencil: Use new_from_existing_style() to create stroke in the modifier.

Gpencil: Add BKE_gpencil_add_stroke_existing_style() function.

This additionally copies the temp drawing color fields in gps->runtime.
So that when adding new strokes in the modifier the style is preserved.

Gpencil: MultiStroke -> Multiple Strokes

Gpencil: Add tip length to length modifier.

So that we can better align the tip points when extending and avoid jittering.
