* Add cluster geometry intrinsics for ray tracing
- Added GetClusterID() method to HitObject class
- Added CandidateClusterID() and CommittedClusterID() methods to
RayQuery class
- Added SPV_NV_cluster_acceleration_structure extension support
- Added GL_NV_cluster_acceleration_structure extension support
- Added test files for RayQuery and HitObject cluster methods
Fixes #6431

* 6431 - Fix spirv opcode
* Remove tests
* Add relevant tests
* Review - Simplify testsUpdate spirv-header and spirv-tools to Jun/2024 (#4679)2024-07-18T20:21:12+00:00Jay Kwak82421531+jkwak-work@users.noreply.github.com2024-07-18T20:21:12+00:00urn:sha1:ad379b7c532bef5ac49e6d730027ac8751e618d7
The following external directories are updated.
It is to use a new SPIRV keyword, "OpExtInstWithForwardRefs".

> Add KHR suffix to OpExtInstWithForwardRef opcode. (#5704)
> The KHR suffix was missing from the published SPIR-V extension.
> This is now fixed, but requires some patches in SPIRV-Tools.

The following PR implements raytracing extensions (GLSL_EXT_ray_tracing, GLSL_EXT_ray_query, GLSL_NV_shader_invocation_reorder & GLSL_NV_ray_tracing_motion_blur); for GLSL & SPIR-V targets. Fully implements all functions, built-in variables, & syntax; resolves #3560 for GLSL & SPIR-V Targets.
notes of worth:
* __rayPayloadFromLocation, __rayAttributeFromLocation, and __rayCallableFromLocation, were added as SPIR-V Intrinsics to refer to location's of raytracing objects in SPIR-V for when using GLSL syntax.
