Although we cached hashes of `MeshVertexBufferLayout`, we were paying the cost of `PartialEq` on `InnerMeshVertexBufferLayout` for every entity, every frame. This patch changes that logic to place `MeshVertexBufferLayout`s in `Arc`s so that they can be compared and hashed by pointer. This results in a 28% speedup in the `queue_material_meshes` phase of `many_cubes`, with frustum culling disabled. Additionally, this patch contains two minor changes: 1. This commit flattens the specialized mesh pipeline cache to one level of hash tables instead of two. This saves a hash lookup. 2. The example `many_cubes` has been given a `--no-frustum-culling` flag, to aid in benchmarking.

Code that was using `MeshVertexBufferLayout` may need to be updated to use `MeshVertexBufferLayoutRef` instead. |
