LineArt: Better handling of boundary cases.

For lineart_LineIntersectTest2d, it fixes the output to 0 or 1 when it's
close enough, gives correct range for point_on_triangle identification.

Then it gives more information through aAligned, which will be true if
two lines completely align, this helps later identification.

Finally: it handles complex cases where one point is on the edge of
a triangle while another point is on the outside.

LineArt: Point on segment logic correction.

The old code would return true when three points happens to be
on X-Y perpendicular placement, now it handles the case correctly.

LineArt: view vector fix for ortho back face.

GPencil: Fix(unreported) Dash modifier wrong logic.

When the modifier iterates to an empty layer with no frame it will return,
while the correct logic is to continue.

Fix(unreported): LineArt curve objects garbled result.

This is caused by line art loading curve objects twice from curve and converted mesh instances (when instance option is on). Now only load mesh when instance option is on.
