* Back out "Update SPIRV submodules (#5815)"
This backs out commit e50aac13e2c161d672b137a62f6d66820d0f9ff1.
* Use upstream spirv-tools
* Fix bump-glslang.sh for newer versions of spirv-tools
* Use upstream glslang
* Add --do-fetch option to bump glslang
* Bump glslang and friends
Supersedes https://github.com/shader-slang/slang/pull/5815
* Regenerate glslang and spirv-tools outputs
* Fixes to slang-glslang
* Correct spirv intrinsic for OpImageSampleFootprintNV
Note that this currently fails validation with the following error:
```
error: line 145: Result <id> from OpSampledImage instruction must not appear as operand for OpImageSampleFootprintNV, since it is not specified as taking an OpTypeSampledImage. Found result <id> '55[%sampledImage]' as an operand of <id> '56[%resultVal]'.
%sampledImage = OpSampledImage %54 %51 %40
```
This seems to be in error as the spec for
*SPV_NV_shader_image_footprint* states that "Sampled Image must be an
object whose type is OpTypeSampledImage"
https://refined-github-html-preview.kidonng.workers.dev/KhronosGroup/SPIRV-Registry/raw/refs/heads/main/extensions/NV/SPV_NV_shader_image_footprint.html
glslang also seems to fail with the same validation error
* Fix spv storage class test

* Allow only specific spv storage classes for binding decoration
In
https://registry.khronos.org/vulkan/specs/1.3/html/chap37.html#VUID-StandaloneSpirv-DescriptorSet-06491
it states that
If a variable is decorated by DescriptorSet or Binding, the Storage
class must be UniformConstant, Uniform and StorageBuffer.
So apply this rule to our emit-spirv logic.
* Add a unit test
* Address few comments
