LineArt: Disable modifier when source/target isn't properly set

Add UV vertices to the newly created mesh.

The mesh->mloopuv has the correct vertices, however it hits
the assert at `(uniform), function GPU_batch_uniform_4fv,`
`blender/source/blender/gpu/intern/gpu_batch.c, line 617.`
if one switches to UV editing workspace.

LineArt: Do not block the process when applying modifier with auto update turned off.

Exporter: Fix UV vertex indices off by one.

Merge branch 'master' into soc-2020-outliner

Minor refactor

PointCloud: Change visualization to use octahedron

This reduces the number of polygon needed. Also optimize
the case when pointcloud has uniform radius.

PointCloud: Initial rendering support for Workbench

Also includes outline overlays. Removes the temp overlay drawing

We make the geometry follow camera like billboards this uses less
geometry. Currently we use half octahedron for now. Goal would be
to use icospheres.

This patch also optimize the case when pointcloud has uniform radius.
However we should premultiply the radius prop by the default radius
beforehand to avoid a multiplication on CPU.

PointCloud: Make geometry follow camera

A bit like billboards. This will allow to use less geometry
in the future.

LineArt: Fix multiple calls to clearing frame when have multiple modifier on baking.

LineArt: use DEG_OBJECT_ITER_FOR_RENDER_ENGINE_BEGIN to support instanced collections and view layer flag.

LineArt: Remove LRT_ENABLED flag.
