49d7985a85 [shaders] Add "compile argument" functionality for generic parameters consumed by compile backends, along with helper to set both a compile arg AND define for cases which require both. The purpose of this is to move towards enforcing that preprocessor defines should _only_ be used during the preprocessing phase itself; the subset of defines that are currently used only as arguments to the compile backends (or used as both actual preprocessor defines and backend arguments) should use this mechanism instead. This allows us to explicitly identify and hash such parameters to be included in a stable key based primarily on a hash of preprocessed/deadstripped source; without it we would need to hash all defines which will defeat most of the deduplication benefit of doing this. A subsequent change will deprecate the GetDefinitions function on the shader compilation environment to enforce that defines cannot be read by anything outside of core shader system functionality.

5a8a3b3063 Unify shader debug name in shader code output for DXC backends to improve cache hits. 
The shader code output contains a little bit of plaintext such as I/O identifiers and the shader name, which was generated for the DXC backend in a way that prevents caching.
This unifies the shader name in the output code and improves the cache hit ratio for a Lyra cook from 0% to roughly 50% cache hits (for certain platforms).

a4b446428f VulkanRHI: Override ShaderParameterParser for Vulkan bindless resource declarations. Use a typedef for each resource's type and declare its variable array with that type, at the end (in SPIRV) collapse all the arrays of a same descriptor type on the same binding. Move 'per-stage' uniform buffer bindings into descriptor sets AFTER the descrciptor sets for the resource arrays (since the resource array bindings will never change, but the ubo will change at a very high frequency). Also add the possibility for platform common headers to overload UB_RESOURCE_MEMBER_RESOURCE to match the altered declaration in ShaderParameterParser (temporary solution). The result gets around the lack of ResourceDescriptorHeap in Vulkan. (Vulkan Bindless WIP)

408b0b8553 Ray Tracing: Compute the maximum payload size from the shader's payload type 
Serialize the payload size as part of the raytracing shader so it can be examined in the RHI layer.

Validate that the RTPSO is configured with the appropriate payload size.

Add macros to ensure the payloads have the expected size

Ensure that all raytracing pipelines explicitly bind a miss shader

Add a shared shader header to implement static asserts for those shader compilers that support them (like dxc).

Fix payload type on main deferred reflection raygen shader

Fix incorrect raygen shader included in the deferred RTPSO list for RTGI

Don't add builtin shaders to the RTPSO from the RHI layer as these are unlikely to ever match the required payload type

Add new method to register payload types so that plugins can more easily describe custom payloads they may be using (up to a maximum of 32 unique payload types since we use a bitmask to represent payload sets).
