Describe the pull request

This PR introduces several API improvements:

  • DeviceState allows to let the device manage resources, namely render passes, pipelines, buffers, images, samplers and descriptor sets.
  • Apps can now be configured with multiple backends per backend type. Using device states help to manage resources over multiple backends.
  • The builder interface has been improved and is now less intrusive, as well as more compatible. This also helps when creating states for multiple backends from a single (template) method.

Device state resources also can be assigned a name now, which is also a preparation for #15.

ToDo

Currently, it is not possible to switch from DX12 back to Vulkan, since D3D12 only supports flip-model based swap chains and there is no way to reset the window afterwards. To fix this, the Vulkan swap chain should interop the DXGI swap chain if the DX12 backend is available. This should also improve performance for Vulkan, since it does not rely on legacy GDI bitblt anymore.

Also the readme and documentation should be adapted before merging.
