Instead make the output VelocityPrevScreenPosition interpolant INVARIANT which is a better match for the other approaches to INVARIANT in the shader code.
Initially the USE_WPO_PRECISE code was added for DXBC only, to prevent mismatch between depth and base pass. This type of error was later more widely fixed by 19392831.
This fix led to another need for USE_WPO_PRECISE. That came from the output position now being (correctly) INVARIANT but the output VelocityPrevScreenPosition didn't have INVARIANT. This could lead to very different calculations between current and previous position and therefore incorrect velocity vectors.

Since the cbuffer uses the same name as the struct, we have to rename the cbuffer using a consistent prefix. The reflection handling also needs to reinterpret the renamed cbuffer as the correct UniformBuffer.

Use MakePrecise() on WPO
This was happening for FXC compiler but not DXC compiler.
It was causing broken velocity vectors, and broken editor outlines on SM6.

- Adding ID3D12DynamicRHI and ID3D11DynamicRHI interfaces for plugins that want to touch DirectX resources/devices directly.
- Adding specific headers for including DirectX headers: D3D12ThirdParty.h and D3D11ThirdParty.h
- Modifying plugins that were using D3D11RHIPrivate.h and D3D12RHIPrivate.h to use the interfaces instead.
- Removing plugin references to UE Modules and ThirdParty libraries that were only needed because they included the private RHI headers.
- Removing D3D11RHI/Private and D3D12RHI/Private from plugin include paths.

We can't share DDPI infrastructure with PC D3D ES3.1 because of conflicts from sharing. We need a separate shader platform.
For now, we'll just 'intrusively' plumb the new Hololens shader platform. In the future, we want to move as much code out into
Hololens-specific platform code to reduce conflict with shared paths that don't need to know about Hololens.
