T88352: Use threaded ibo.tris extraction for single material meshes.

This patch adds a specific extraction method when the mesh has only
one material. This method is multi-threaded.

There is a trade-off in this patch as the ibo isn't compressed (it adds
restart indexes for hidden faces). So it depends if threading is faster
than the additional GPU buffer upload.

# Subdivided cube
I used a cube subdivided 7 times, modifiers applied. that gives around 400000 faces.

The test is selecting some vertices and move them. During this test the next buffers are updated on each frame:
* vbo.pos_nor
* vbo.lnor
* vbo.edit_data
* ibo.tris
* ibo.points
