[SPIR-V] Specify target environment in tests referring to the BuiltIn WorkgroupSize variable (#122755)

KhronosGroup/SPIRV-Tools#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.
