Force Textures to be Optimal on Host GPU

Browse Source 
We don't respect the host subresource layout in synchronizing linear textures from the guest to the host when mapped to memory directly, this leads to texture corruption and while the real fix would involve respecting the host subresource layout, this has been deferred for later as real world performance advantages/disadvantages associated with this change can be observed more carefully to determine if it's worth it.
