Draw Cache: extract tris in parallel ranges

The `ibo.tris` extraction in multithread is currently only done if the
mesh has only 1 material.

Now we cache a map indicating the index of each polygon after sort and
thus allow the extraction of tris with materials in multithreaded.

As caching is a heavy operation and was already being performed in
multi-thread for triangle offsets, no significant improvements are
expected.

The benefit will be much greater when we can skip updating the cache
while transforming a geometry.
