D3D11: Implement polyfill of DP4A

This patch implements the polyfill versions of `dot4I8Packed()` and
`dot4U8Packed()` and uses them on the D3D11 backend. In the next
patch they will also be used on the D3D12 and Vulkan backends where
the DP4A instructions are not supported in native HLSL or SPIRV.
