Resolve Clang-Vulkan validation error `VUID-VkShaderModuleCreateInfo-pCode-08742`

[bob80905]

The distance.fp16.test and distance.32.test tests do not support clang-vulkan due to a validation error.
When running these tests, this error output is seen:

# .---command stderr------------
# | Validation Error: [ VUID-VkShaderModuleCreateInfo-pCode-08740 ]

In both validation errors, there are missing requirements.
The offload test suite needs a way to specify these requirements, so that these tests can be run.
This issue tracks the two tests listed above, while they're run in clang-vulkan unsupported mode. They should be run in clang-vulkan as well.
