Fix: Deselecting edges in sticky vertex mode

Fixes the bug where deselecting an UV edge in sticky vertex mode would
deselect the UV vertices as well.

LineArt: Better smoothing algo.

Fix memory leak in non primitive collision shape

- The previous commit didn't fix the leak as the mesh data was not being freed every draw call
- Now the mesh is generated during evaluation along with the physics shape.
- The collisions shape draw data mesh is stored in the shared struct, along with the physics references

Support opening and collapsing tree-view items

For this to work, we need to support tree-view items with state that is
persistent over redraws. This is achieved by matching tree items to tree
items of a previous redraw, and copying the state if needed. This is
done in the tree-view API, so except for more advanced cases (with
custom item state or custom ways to match items), API users shouldn't
have to deal with this.

Fix crash denoising shadow catcher in Cycles X

Fix missing render progress on Windows in Cycles X

The issue is caused by `::wglShareLists()` returning an error if the
shared context is currently in use, so that the OpenGL context for
GPUDisplay did fail to be created.

After a lot of experimentation all the non-intrusive changes to support
OpenGL context creation with shared textures has failed.

The easiest way to have reliable OpenGL context creation is to do it on
the main thread.

For the offline rendering this is done in the pipeline.c. This change
takes advantage of this and uses the Render::gl_context for the GPU
display implementation for offline rendering.

For the viewport rendering we don't have Render, but the engine is
created from the main thread, so we can create context from the Cycles
side.

Not really happy with such approach, but this seems to be easiest and
safest way to go for now to get other bits of Cycles X finished. In the
future Vulkan should make things easier for the context creation and
multi-threaded applications.
