- Support structured buffers in HLSL backend of SPIRV-Cross (PR #2143).
- Integrate SPIRV-Cross fix to forward opaque types in GLSL backend (PR #2110).
- Integrate SPIRV-Cross fix to use actual field offset to validate vec4 boundary alignment (#PR 2139).
- Integrate SPIRV-Cross fix to not restrict SV_RenderTargetArrayIndex to GS and MS (#PR 2138).
- Make SV_Position decoration as implicitly invariant optional (Used to address Z-fighting issues in Vulkan and Metal; Drastically impacts vertex shader performance on certain platforms).
- Don't force DXC for all shaders when r.Substrate is enabled.

- each platform compilation request is now wrapped in __try/__except rather than a single exception handling block at the top level of the worker; this allows us to log an exception (with callstack) as a compilation error and continue the batch
- remove SEH code from ShaderConductorContext, the above makes this redundant (and it didn't provide any actionable information)
- strip down SEH code in D3DShaderCompiler; now only used for the purposes of pre-compiling with DXC in the case of an FXC crash. dumping preprocessed source will be handled in a different manner in a forthcoming CL
- minor change in the DXC precompile path to not log an unnecessary warning when performing an explicitly-requested DXC precompile

Also remove further references to Hull and Domain shaders as tessellation is no longer supported in UE5.
