Some changes to VertexLoaderManager:

Browse Source 
- Lazily create the native vertex format (which involves GL calls) from
RunVertices rather than RefreshLoader itself, freeing the latter to be
run from the CPU thread (hopefully).

- In order to avoid useless allocations while doing so, store the native
format inside the VertexLoader rather than using a cache entry.

- Wrap the s_vertex_loader_map in a lock, for similar reasons.
