[SYCL][L0] Return maximum group size in L0 for info::kernel_device_specific::work_group_size (#7693)

Level-zero currently implements
kernel.get_info<info::kernel_device_specific::work_group_size> by
calling zeKernelSuggestGroupSize which gives a group size suggestion
based on a global size. This seems to be against specification where the
descriptor requires the maximum work items available for execution in a
group
