https://github.com/KhronosGroup/SPIRV-Tools/pull/5407 introduces a check for WorkgroupSize variable to be a 3-component 32-bit int vector, and indeed, we see this requirement in https://registry.khronos.org/vulkan/specs/latest/man/html/WorkgroupSize.html#VUID-WorkgroupSize-WorkgroupSize-04427 However, OpenCL imposes different requirements, documented here: https://registry.khronos.org/OpenCL/specs/3.0-unified/html/OpenCL_Env.html#_built_in_variables OpenCL environment requires WorkgroupSize variable to have components of size_t size that will be 32 or 64 depending on a target. This is the way how the SPIR-V Backend implements this, by querying pointer size of the current platform/target. To allow spirv-val to account target environments difference, this PR adds `--target-env <env>` to test cases referring to the BuiltIn WorkgroupSize variable.
