Updates for final Vulkan ray tracing extensions (#2466)
* Fix traceRay/executeCallable to have id instead of constant.

Update to final (non-provisional) SPIR-V capabilities
(includes review feedback)
- Change visibilty of findLinkerObjects.

See merge request GLSL/glslang!78

* Add support for OpConvertUToAccelerationStructureKHR.

GLSL : https://gitlab.khronos.org/GLSL/GLSL/-/merge_requests/60

SPV : https://gitlab.khronos.org/spirv/spirv-extensions/-/merge_requests/182

See merge request GLSL/glslang!77

* Add volatile qualifier to certain builtins for ray tracing.

See merge request GLSL/glslang!81

* make gl_RayTmaxEXT volatile in intersection shader

Vulkan Issue #2268

* Add testing for layouts on SBT

vulkan/vulkan#2230

- no layout specified should be same as std430
- explicitly test std140, std430, scalar layouts

See merge request GLSL/glslang!86

* Support for new opcodes OpIgnoreIntersectionKHR and OpTerminateRayKHR

vulkan/vulkan#2374

Add support for ignoreIntersectionEXT and terminateRayEXT as block
terminator statements.

See merge request GLSL/glslang!87

* Fix code-generation issues with global ray query variables

See merge request GLSL/glslang!88

* update dependencies for spirv-headers and tools

And update mesh shader results

* Fix indeterminate argument ordering

2cb2f197a7 Add support for GL_NV_shader_sm_builtins
Including spirv and AST tests

Also increase size of TBuiltInVariable bitfields since we've now exceeded 127
and add a static_assert to make this easier to find next time it happens!

593a4e0aa5 Fix subgroup support for ray tracing
Closes #1735

GlslangToSpv.cpp
- minor formatting cleanup

BaseTypes.h
- minor formatting cleanup
- add subgroup builtins to GetBuiltInVariableString
  (was resulting in "unknown built-in variable" messages in test output)

Initialize.cpp
- better naming and re-use of strings for subgroup builtin variable declarations
- define subgroup builtin variables in ray-tracing shaders

intermOut.cpp
- add handling of the EOpSubgroupParition* variables
  (was resulting in "ERROR: Bad aggregation op" messages in test output)

Update test results.

c3e60ad9b6 Add AST tests for ray tracing shaders
with subgroup touch tests (error and non-error cases)
Currently the subgroup built-ins are NOT giving the correct output.
This is fixed in the next commit.
