sub_group_sycl2020.cpp test is currently marked as unsupported for CUDA due to missing support for kernel-bundles. This patch adds a special CUDA path for avoiding the use of kernel-bundles, using the known size of sub-groups instead of querying for it.
This is a temporary work-around and can be reverted once kernel-bundle support is added in the PI CUDA backend.
