Using `local_size_x = 512` in the shader used in the Vulkan interop tests fails on older hardware because this exceeds the maximum barrier size limit. Changed to 256, which is still a multiple of 32 and 64, and is below the hardware limitations. The tests are not performance tests anyways, so the performance penalty, if any, is acceptable.
