Publishing the DXR Samples and Raytracing Fallback Layer.

There's 3 primary components:
 * The D3D12 Raytracing Fallback Layer is being placed in it's entirety in libraries/D3D12RaytracingFallbac
 * The DXR Samples are being placed in Samples/Desktop/D3D12Raytracing/src
 * A modified version of the MiniEngine's ModelViewer called the D3D12RaytracingMiniEngineSample. It uses the Fallback Layer for a variety of raytracing effects on the Sponza scene.

Users looking to get started can open up the project in Samples\Desktop\D3D12Raytracing\src\D3D12Raytracing.sln

Users will need to also overlay dxcompiler.dll binaries with the samples. These will be provided in the DirectX-Graphics-Samples via the releases tab in regular drops. The drop corresponding to this commit is DirectXRaytracingBinariesV1.0.zip. A script has been integrated into the solution that makes sure users are informed when these are missing and where to get them.

…p Level Acceleration Structures (#297)

This adds support for local root signatures/shader records with descriptor table handles as the parameter. This removes the need for the app having to do it's own bindless indexing to associate a ClosestHit shader with a texture.

Also adding tests for verifying the use of descriptor tables. These tests have a pass-through raygen trace against a null acceleration structure and invoke the varying miss shaders that test different varieties of descriptor tables pulled from the shader record.

Finally, modifying the MiniEngine sample to use descriptor tables as local root signature arguments, which cleans up the shader code nicely.

…ce (#298)

* Added a base for a ProceduralGeometry sample.

* Pass through Intersection with reporting a hit for the whole AABB.

Updating the Fallback Layer to handle procedural geometry (intersection shaders) . Most of the change is based around updating Bottom Level Acceleration Structures that were previously hard-coded to assume all primitives were triangles. Adding an extra flag that now marks whether a primitive is a triangle or a procedural geometry.

Follow-up work:
 * Testing for intersection shaders is limited and currently only verified through the D3D12ProceduralGeometry sample
 * Unlike triangles, procedural geometry don't have any underlying data (i.e. vertices) that need to be stored per leaf. Currently space is allocated as-if procedural geometry does need this space (simplifies some early BVH construction code) , but this could be optimized for memory usage.

Added AABBs with matrix transformations.
Added shadows.

BLAS with AABBs is now instantiated multiple times within TLAS.

…es in the Traversal shader when Intersection Shaders are active (#309)

… drivers (#310)

Fixing several issues:
Payload size is incorrectly calculated
Moving global root constants to root views to avoid a known driver issue
Resource state not correctly set for bottom levels
Currently still a known issue where diffuse textures in shader records aren't correctly loaded for native drivers

…flags (#321)

…#325)

…han group-shared (#328)

Modifying the BVH stack to be stored on regular per-thread data. This was a premature optimization that currently shows no perf difference and the saving and restoring of data from groupshared memory, particularly since there's no sharing of data between threads.

…e reflection pass unitentionally recursively trace shadow rays (#329)

…e devices

Adding the globallycoherent tag on resources that depended on writes from other waves after a device barrier. Fixes a TDR that was happening on some devices.
Also bundling in a fix where a CComPtr's &operator would be used with non-null contents on RS5 builds.

…tion/anyhit shader is active

Adding a workaround in lieu of API-specified stack support (significant amount of dev required) to allow for the procedural geometry sample to run properly.
The underlying issue is using intersection shaders introduces a continuation with the Traversal shader, which introduces a large amount of live-values that wouldn't normally get hit in cases with no anyhit/intersection shaders
