More aggressive data-oriented design for ECS

[matt77hias]

More aggressive data-oriented design, less object-oriented design for ECS.

Major steps:

• Redesign ECS: Entity (i.e. U64) <-> Component links are maintained via multiple ComponentManagers instead of the Entities themselves.
• Move ECS to Utilities (+ remove Core?).
• Redesign the current Mesh/Model with animations in mind (+ provide an adapter for Assimp).

At the same time D3D11 can be replaced with D3D12 (or with D3D12 in mind at least).
