Fix invalid bit shift when GPU shader attribute is not found

Fix NULL pointer access reported by ASAN (harmless in practice but still weak)

Fix potential crash due to dyntopo GPU buffer invalid memory access

When the number of triangles in a node became zero, the wireframe batch was
not freed along with the triangles batch and could still reference a freed
vertex buffer.

Ref T76858

Fix T76813: Snap to Edge Center returning a different normal from snap to Edge

This difference was intentional, but using the edge direction as normal is more useful.

Refactor: Move workspace foreach_id to new IDTypeInfo structure.

Make initial initialization faster

Draw active keyframe differently in dopesheet

Move active graph vertex drawing to separate functions

Refactor: Move WindowManager and Screen foreach_id to new IDTypeInfo structure.

That one was a bit more complicated, and is still only partial refactor
(ultimately we want to have a foreach_id callback in SpaceType itself I
think...).

Refactor: Move action foreach_id to new IDTypeInfo structure.

Change set active logic

Fix part of T76544: dyntopo sculpt undo stack memory leak

OIpenSubdiv: Cleanup, move to a better sounding namespace

The code is not only part of C-API, but also implements Blender-specific
glue level implementation.

Fix T76814: [Mantaflow] Surface Tension always works

Initialize the curvature grid and compute the laplacian only if the diffusion flag is set.

OpenSubdiv: Cleanyp, remove old GPU code

All parts of drawing (shaders, GL mesh descriptor, material partitioner
and so on) needs to be redone for the draw manager and new OpenSubdiv
library.

Removing untested code which is doomed to be replaced to make localized
refactoring easier.
